8.3.1 Enable and Shutdown Input (EN/SHDN)

The TPS1641x devices include a enable and shutdown input. Keeping EN/SHDN low for a duration more than tLow_SHDN brings the device into low power shutdown mode, internal blocks of device are turned off, and the quiescent current of the device is reduced to IQSD from Vcc supply.

While keeping EN/SHDN low for a duration less than tLow_SHDN, the device turns off the internal FET only and FET can be turned back on quickly. The device turns off the internal FET with a delay of tEN_OFF_dly as the enable pin is brought low. The internal FET can be enabled quickly with a delay of tEN_ON_dly when the device is not in shutdown.

The TPS1641x is an integrated eFuse with accurate power limit or current limit. The device integrates an NFET with RON of 152 mΩ. TPS16410, TPS16411, TPS16414 and TPS16415 provide power limiting whereas the TPS16412, TPS16413, TPS16416 and TPS16417 provide current limiting. The TPS16410, TPS16411, TPS16414 and TPS16415 can provide 15-W accurate power limiting for low power circuit (LPCs) as per IEC60335 and UL60730 standards. TPS16410, TPS16411, TPS16412 and TPS16413 also provide IN to OUT short detection and its indication on FLT output. IN to OUT short detection eliminates the need of additional eFuse or power limiting circuit in case of IN to OUT short test for IEC60335, UL60730, and similar standards. FLT can be used as input for MCU or it can be used to drive an external PFET. TPS1641x devices also provide protection from adjacent pin short and pin short to GND faults. The TPS1641x device also provide configurable blanking time (IDLY or PDLY) and overcurrent protection (IOCP) for transient loads. Load such as motors need higher current for start-up. Blanking time is useful for providing higher current for start-up of loads such as motors. TPS1641x devices have overvoltage protection (OVP), overtemperature protection, and adjustable output slew rate control (dvdt). Vcc and FLT are rated up to 60 V and can provide protection up to 60 V with an external PFET. Functional Block Diagram Feature Description Enable and Shutdown Input (EN/SHDN) The TPS1641x devices include a enable and shutdown input. Keeping EN/SHDN low for a duration more than tLow_SHDN brings the device into low power shutdown mode, internal blocks of device are turned off, and the quiescent current of the device is reduced to IQSD from Vcc supply. While keeping EN/SHDN low for a duration less than tLow_SHDN, the device turns off the internal FET only and FET can be turned back on quickly. The device turns off the internal FET with a delay of tEN_OFF_dly as the enable pin is brought low. The internal FET can be enabled quickly with a delay of tEN_ON_dly when the device is not in shutdown. See the for VENR and VENF thresholds and the for tLow_SHDN, tEN_OFF_dly, and tEN_ON_dly timings. A PWM signal with low period less than tLow_SHDN can be provided on EN/SHDN pin of the device for fast turn-on and turn-off of internal FET. illustrates the EN/SHDN input in the TPS1641x devices. shows the start-up of the device with enable input. EN/SHDN in TPS1641x Devices Turn-On with Enable VIN = 12 V Overvoltage Protection (OVP) The TPS1641x implements overvoltage protection to protect the load from input overvoltage conditions. A resistor divider can be connected from the IN pin of device to configure the overvoltage protection setpoint. The device turns off the internal FET and asserts the FLT pin as the voltage at OVP pin goes above VOVPR, and as the OVP pin voltage falls below VOVPF, the internal FET is turned ON and FLT pin is de-asserted. See the table for VOVPF and VOVPR­ and for tOVP_entry_dly and tOVP_exit_dly timings for overvoltage protection input. illustrates the OVP input in TPS1641x devices. shows the overvoltage response. OVP Input in TPS1641x Overvoltage Protection Response for IN Voltage 12 V to 40 V Vcc and FLT pins of the device are rated up to 60 V, and the FLT pin can be used to drive an external PFET transistor and provide protection from 60-V overvoltage at input as shown in . Overvoltage (up to 60 V) Protection with External PFET To disable the overvoltage input, connect OVP to GND. If the OVP pin is left open, the device turns off the internal FET. Overvoltage Response with External PFET for IN Voltage from 12 V to 60 V Hot Plugin with External PFET for 60-V Input Output Slew Rate and Inrush Current Control (dVdt) During hot plug events or while trying to charge a large output capacitance, there can be a large inrush current. If the inrush current is not managed properly, it can damage the input connectors and cause the system power supply to droop leading to unexpected restarts elsewhere in the system. The inrush current during turn-on is directly proportional to the load capacitance and rising slew rate. can be used to find the output slew rate (SR) required to limit the inrush current (IINRUSH) for a given output capacitance (COUT). S R   =   I I N R U S H C O U T A capacitance can be added to the dVdt pin to control the rising slew rate and lower the inrush current during turn-on. The required CdVdt capacitance to produce a given slew rate can be calculated using . C d V d t   =   I d V d t   ×   G d V d t   S R The fastest output slew rate is achieved by leaving the dVdt pin open. If dVdt pin is connected to GND, the device will not power up the output. illustrates the output slew rate control in the TPS1641x devices. shows the output slew rate control response of the device. Output Slew Rate Control in the TPS1641x Output Slew Rate Control with VIN = 12 V, CdVdt = 150 nF, and COUT = 470 μF Active Current Limiting (ILIM) With the TPS16412, TPS16413, TPS16416, and TPS16417 B 20230421 Added new device variants no The TPS16412, TPS16413, TPS16416, and TPS16417 devices respond to output overcurrent or overload conditions by actively limiting the current. The devices first provide a blanking time configured by capacitance on the IDLY pin. During this blanking time, the device can provide a current up to IOCP value. After the end of this blanking time, the devices limit current to ILIM value. ILIM can be set by connecting resistor on ILIM pin. RILIM can be calculated by . I L I M =   0.984   A R I L I M     ×   10   k Ω If the output current exceeds IOCP, the device goes into current limiting. During current limiting, if the output current goes below ILIM (IOUT < ILIM), the device resets the IDLY timer and restarts IDLY timer when IOUT > ILIM. illustrates the current limiting behavior for IOUT < IOCP and for IOCP ≤ IOUT < Ifast-trip. During current limiting, if the output current goes below ILIM (IOUT < ILIM), the device resets the IDLY timer and restarts the IDLY timer when IOUT > ILIM. Current Limiting for IOUT < IOCP IOCP ≤ IOUT < Ifast-trip During the current limiting, the device dissipates a power of (VIN – VOUT) × IOUT and the device gets heated up. If the junction temperature of device reaches thermal shutdown temperature (TTSD), the device turns off the internal FET. If the device does not go into thermal shutdown, the internal FET is turned off after a duration of tILIM-DUR. After the internal FET is turned off, the TPS16412 and TPS16416 auto-retry while the TPS16413 and TPS16417 latch off. If ILIM pin is connected to GND or left open, the device turns-off the internal FET. If the IDLY pin is left open or connected to GND, device provides tILIM-DUR = 155 ms unless the device enters thermal shutdown. summarizes the device behavior for different output currents. Current Limiting and Overload Protection With TPS16412, TPS16413, TPS16416, and TPS16417 Output Current (IOUT) Device Response IOUT < ILIM The device provides current up to ILIM. ILIM ≤ IOUT < IOCP The device provides current up to IOCP for a duration of IDLY and then limits current to ILIM for a maximum duration of tILIM-DUR. IOCP ≤ IOUT < Ifast-trip The device limits current to ILIM for a maximum duration of tILIM-DUR. Ifast-trip ≤ IOUT < ISCP The device turns off the internal FET after a delay of tfast-trip. ISCP ≤ IOUT The device turns off the internal FET after a delay of tSCP_dly. Active Power Limiting (PLIM) With the TPS16410, TPS16411, TPS16414, and TPS16415 B 20230421 Added new device variants no The TPS16410, TPS16411, TPS16414, and TPS16415 devices respond to output overcurrent or overload conditions by actively limiting the output power. The devices first provide a blanking time configured by capacitance on PDLY pin. During this blanking time, the device can provide a current up to IOCP value. After the end of this blanking time, the devices limit power to PLIM value. Power limit can be set by connecting a resistor on the PLIM pin. During power limiting, if the output power goes below PLIM (POUT < PLIM), the device resets the PDLY timer and restarts the PDLY timer when POUT > PLIM. Use to calculate the value of resistor for power limiting. The device is rated for 1.8-A continuous current, TI recommends to set PLIM < VIN × 1.8 A and PLIM < 0.9 × VOUT × IOCP P L I M =   13.82   W 95.3   k Ω   ×   R P L I M illustrates the power limiting in the TPS16410 and TPS16411 devices for IOUT < IOCP and IOCP ≤ IOUT < Ifast-trip. Power Limiting (IOUT < IOCP) Power Limiting (IOCP ≤ IOUT < Ifast-trip) During power limiting, the device dissipates a power of (VIN – VOUT) × IOUT and the device gets heated up. If the junction temperature of device reaches thermal shutdown temperature (TTSD), the device turns off the internal FET. If the device does not go into thermal shutdown, the internal FET is turned off after a duration of tPLIM-DUR. After the internal FET is turned off, the TPS16410 and TPS16414 devices auto-retry while the TPS16411 and TPS16415 device latch off. If PLIM is connected to GND or left open, the device turns-off the internal FET. If the PDLY pin is left open or connected to GND, device provides tPLIM-DUR = 155 ms unless the device enters thermal shutdown. summarizes the device behavior for different output power and current. Power Limiting and Overload Response in TPS16410, TPS16411, TPS16414, and TPS16415 Devices Output Power (POUT) or Output Current (IOUT) Device Response POUT < PLIM The device provides power up to PLIM. PLIM ≤ POUT and IOUT < IOCP The device provides current up to IOCP for a duration of PDLY and then limits power to PLIM for a maximum duration of tPLIM-DUR. IOCP ≤ IOUT < Ifast-trip The device limits current to PLIM for a maximum duration of tPLIM-DUR. Ifast-trip ≤ IOUT < ISCP The device turns off the internal FET after a delay of tfast-trip. ISCP ≤ IOUT The device turns off the internal FET after a delay of tSCP_dly. Internal Current Limit for the TPS16410 and TPS16411 B 20230421 Added new device variants no In power limiting devices, there is an internal current limit. If during power up, the output current exceeds overcurrent protection setpoint (IOCP), these devices limit current to 0.81 × IOCP. TPS16410, TPS16411, TPS16414, and TPS16415 devices also limit the output current if PLIM is set to more than (VOUT × IOCP) and IOUT exceeds IOCP. Overcurrent Protection (IOCP) and Blanking Time (IDLY or PDLY) for Transient Loads In TPS1641x devices, the overcurrent protection set-point can be configured by connecting a resistor on IOCP pin. The resistor value for overcurrent can be calculated by #GUID-CEE5453C-3447-4C14-B02F-0B8783EC71CF/GUID-A9DDCAA1-1BA5-4DF1-B822-A1084D0ABB08. I O C P =   2.25   A R I O C P     ×   7.32   k Ω If the IOCP pin is left open or connected to GND, the device turns off the internal FET. The devices also provide blanking time for overload or overcurrent events. This blanking time can be configured by connecting a capacitor on IDLY or PDLY, and the blanking time can be calculated by #GUID-CEE5453C-3447-4C14-B02F-0B8783EC71CF/GUID-7B6743B8-5B89-4D39-B409-D5561E258CFF. If IDLY/PDLY pin is left open or connected to GND, device disables the blanking time and directly goes into power or current limiting.

When an output short-circuit is detected and output current reaches ISCP level, the device turns off the internal FET after a delay of tSCP_dly. In case of fast input transients, the current through internal FET rises rapidly, but these transients can lead to false turn-off of internal FET due to excessive flow of current through internal FET. To prevent false tripping during these input transients, the device includes fast-trip comparator, which turns off the internal FET if the output current exceeds Ifast-trip for a duration of tfast-trip. shows the short-circuit response of the device. Short-Circuit Response with VIN = 12 V Analog Load Current Monitor (IMON) on the IOCP Pin The device allows the system to monitor the output load current accurately by providing an analog current on the IOCP/IMON pin, which is proportional to the current through the FET. The resistor on IOCP/IMON pin converts this current into voltage and this voltage can be used for monitoring the output current.

Keeping EN/SHDN low for a duration more than tLow_SHDN brings the device into low power shutdown mode, internal blocks of device are turned off, and the quiescent current of the device is reduced to IQSD from Vcc supply. While keeping EN/SHDN low for a duration less than tLow_SHDN, the device turns off the internal FET only and FET can be turned back on quickly. The device turns off the internal FET with a delay of tEN_OFF_dly as the enable pin is brought low.

A resistor divider can be connected from the IN pin of device to configure the overvoltage protection setpoint. The device turns off the internal FET and asserts the FLT pin as the voltage at OVP pin goes above VOVPR, and as the OVP pin voltage falls below VOVPF, the internal FET is turned ON and FLT pin is de-asserted. See the table for VOVPF and VOVPR­ and for tOVP_entry_dly and tOVP_exit_dly timings for overvoltage protection input. illustrates the OVP input in TPS1641x devices. shows the overvoltage response.

During current limiting, if the output current goes below ILIM (IOUT < ILIM), the device resets the IDLY timer and restarts IDLY timer when IOUT > ILIM. illustrates the current limiting behavior for IOUT < IOCP and for IOCP ≤ IOUT < Ifast-trip. During current limiting, if the output current goes below ILIM (IOUT < ILIM), the device resets the IDLY timer and restarts the IDLY timer when IOUT > ILIM. Current Limiting for IOUT < IOCP IOCP ≤ IOUT < Ifast-trip During the current limiting, the device dissipates a power of (VIN – VOUT) × IOUT and the device gets heated up. If the junction temperature of device reaches thermal shutdown temperature (TTSD), the device turns off the internal FET.

Active Power Limiting (PLIM) With the TPS16410, TPS16411, TPS16414, and TPS16415 B 20230421 Added new device variants no The TPS16410, TPS16411, TPS16414, and TPS16415 devices respond to output overcurrent or overload conditions by actively limiting the output power. The devices first provide a blanking time configured by capacitance on PDLY pin. During this blanking time, the device can provide a current up to IOCP value. After the end of this blanking time, the devices limit power to PLIM value. Power limit can be set by connecting a resistor on the PLIM pin.

If the junction temperature of device reaches thermal shutdown temperature (TTSD), the device turns off the internal FET. If the device does not go into thermal shutdown, the internal FET is turned off after a duration of tPLIM-DUR. After the internal FET is turned off, the TPS16410 and TPS16414 devices auto-retry while the TPS16411 and TPS16415 device latch off. If PLIM is connected to GND or left open, the device turns-off the internal FET.

Internal Current Limit for the TPS16410 and TPS16411 B 20230421 Added new device variants no In power limiting devices, there is an internal current limit. If during power up, the output current exceeds overcurrent protection setpoint (IOCP), these devices limit current to 0.81 × IOCP. TPS16410, TPS16411, TPS16414, and TPS16415 devices also limit the output current if PLIM is set to more than (VOUT × IOCP) and IOUT exceeds IOCP. Overcurrent Protection (IOCP) and Blanking Time (IDLY or PDLY) for Transient Loads In TPS1641x devices, the overcurrent protection set-point can be configured by connecting a resistor on IOCP pin. The resistor value for overcurrent can be calculated by #GUID-CEE5453C-3447-4C14-B02F-0B8783EC71CF/GUID-A9DDCAA1-1BA5-4DF1-B822-A1084D0ABB08.

When an output short-circuit is detected and output current reaches ISCP level, the device turns off the internal FET after a delay of tSCP_dly. In case of fast input transients, the current through internal FET rises rapidly, but these transients can lead to false turn-off of internal FET due to excessive flow of current through internal FET. To prevent false tripping during these input transients, the device includes fast-trip comparator, which turns off the internal FET if the output current exceeds Ifast-trip for a duration of tfast-trip. shows the short-circuit response of the device. Short-Circuit Response with VIN = 12 V Analog Load Current Monitor (IMON) on the IOCP Pin The device allows the system to monitor the output load current accurately by providing an analog current on the IOCP/IMON pin, which is proportional to the current through the FET. The resistor on IOCP/IMON pin converts this current into voltage and this voltage can be used for monitoring the output current. Output current can be calculated from voltage at IOCP/IMON pin by using #GUID-743F91F2-76AD-49F8-AE6D-FF0DB411EC6F/GUID-EA44A692-6D23-44A1-BE93-D8E476299700.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. Application Information TPS1641x devices include power limiting or current limiting for a low power circuit (as per IEC60335 and UL60730 standards) in appliances, HVAC actuators, and medical equipment. TPS1641x devices also have IN to OUT short detection for internal FET for IN-OUT short testing during IEC60335 or UL60730 certifications. The TPS16410 and TPS16411 have an accurate power limiting feature while the TPS16412 and TPS16413 have an accurate current limiting feature. For transient current required for start-up of motors or actuators, TPS1641x devices have a configurable overcurrent protection threshold (IOCP) and configurable blanking time (IDLY/PDLY). For start-up with big capacitance (< 1 mF) on output, the TPS1641x include dVdT feature to control the output slew rate and limiting the inrush current during power up. The output current can be monitored from IOCP or IMON pin, by sensing the voltage on this pin. Typical Application: 15-W Power Limiting for Low Power Circuits (LPCs) The TPS16410 and TPS16411 can be used for 15-W power limiting for low-power circuits in IEC60335 and UL60730 standards. The output power limit can be configured by a resistor on the PLIM pin. provides a typical application circuit for 15-W power limiting. 15-W Power Limiting for Low-Power Circuits Design Requirements Design Parameters Parameter Value VIN 18 V to 32 V POUT ≤ 15 W Overcurrent protection 1 A Output capacitance (COUT) 470 μF IINRUSH ≤ 350 mA Blanking time for transients (PDLY) 6.5 ms Detailed Design Procedure Setting Overvoltage Setpoints Input overvoltage protection setpoints can be set by connecting resistors (R1, R2) from the IN pin to OVP pin. The value of resistors can be calculated using #GUID-E1DF5068-A0C0-4FF5-8AE4-A3F3DEF92878/EQUATION-BLOCK_X4M_ZF3_STB and #GUID-E1DF5068-A0C0-4FF5-8AE4-A3F3DEF92878/EQUATION-BLOCK_TZV_ZF3_STB. To set the OVP rising setpoint to 32 V, R1 = 1 MΩ and R2 = 47 kΩ are selected.

To calculate the value of this resistor (R4), use . For IOCP = 1 A, R4 is selected as 16.2 kΩ. Setting the Output Power Limit For setting the output power limit, a resistor (R3) is required on the PLIM pin. To calculate the value of power limit, use. To keep output power limit ≤ 15 W, R3 was selected as 95.3 kΩ. Monitoring the Output Current The output current can be monitored on IOCP or IMON by reading the voltage on this pin. The output current can be calculated using . Limiting the Inrush Current and Setting the Output Slew Rate For charging the large capacitors on output, the output slew rate can be controlled by using a capacitor on dVdt pin. The value of inrush current can be estimated by #GUID-D88A6004-2EF8-434E-BA27-D6801E7DF9FF/GUID-F96B89FD-DCBD-4096-A701-579C6434AF9D.

For additional protection, the device has a fault pin and it is asserted in case of overvoltage, overcurrent or overpower, IN-short detection and thermal shutdown events. The fault can be used to turn-off the DC/DC converter or flyback converter providing the power to input of TPS1641 for the load. The device has separate Vcc pin for powering itself and it can remain on with Vcc supply. illustrates the application at the output of DC/DC or flyback converter. Accurate Power or Current Limiting at the Output of DC/DC or Flyback Converter Best Design Practices Use CIN ≥ 10 nF for decoupling Vcc and IN pins. Do not leave the OVP, PLIM/ILIM, and IOCP/IMON pins open or floating. Connect the PowerPAD of the device to GND on the PCB. Do not connect the EN/SHDN pin to voltage more than 5 V. Power Supply Recommendations Use 4.5 V ≤ VIN ≤ 40 V for the TPS16410 and TPS16411. Use 2.7 V ≤ VIN ≤ 40 V for the TPS16412 and TPS16413. Use VIN ≤ VCC ≤ 60 V. Pull up FLT with voltage ≤ 60 V. Use a pullup resistor to keep current into the FLT pin < 3 mA. Transient Protection In the case of a short-circuit and overload current limit when the device interrupts current flow, the input inductance generates a positive voltage spike on the input, and the output inductance generates a negative voltage spike on the output. The peak amplitude of voltage spikes (transients) is dependent on the value of inductance in series to the input or output of the device. Such transients can exceed the absolute maximum ratings of the device if steps are not taken to address the issue. illustrates the transient protection circuit. Typical methods for addressing transients include: Minimize lead length and inductance into and out of the device. Use a large PCB GND plane. Connect a Schottky diode (D2) from the OUT pin ground to absorb negative spikes. The OUT pin has an absolute maximum rating of –1 V for negative transient spikes on output. Connect a low-ESR capacitor larger than 1 μF at the OUT pin very close to the device. Use a low-value ceramic capacitor CIN = 0.1 μF to absorb the energy and dampen the transients. The approximate value of input capacitance can be estimated with . V I N - S P I K E = V I N +   I L O A D   ×   L I N   C I N Some applications require additional Transient Voltage Suppressor (TVS) to keep transients below the absolute maximum rating of the device. A TVS can help to absorb the excessive energy dump and prevent it from creating very fast transient voltages on the input of the device. Use a suitable TVS to clamp the transient voltage below the absolute maximum rating of the device. Transient Protection with TPS1641x TVS D1* and Schottky D2* are optional diodes for transient protection on the input and output. Layout Layout Guidelines High current-carrying power-path connections must be as short as possible and must be sized to carry at least twice the full-load current. The GND (PowerPAD) pin must be tied to the PCB ground plane at the terminal of the IC with the shortest possible trace. The PCB ground must be a copper plane or island on the board. TI recommends to have a separate ground plane island for the eFuse. This plane does not carry any high currents and serves as a quiet ground reference for all the critical analog signals of the eFuse. The device ground plane must be connected to the system power ground plane using a star connection. The optimal placement of the decoupling capacitor (CIN) is closest to the IN and GND pins of the device. Care must be taken to minimize the loop area formed by the bypass-capacitor connection, the IN pin, and the GND pin of the IC. Locate the following support components close to their connection pins: RILM or RPLM RIOCP CDLY CdVdT Resistors for OVP Connect the other end of the component to the GND pin of the device with shortest trace length. The trace routing for these components to the device must be as short as possible to reduce parasitic effects on the current limit, overcurrent blanking interval, and soft-start timing. Because the bias current on ILM pin directly controls the overcurrent protection behavior of the device, the PCB routing of this node must be kept away from any noisy (switching) signals. Protection devices such as TVS, snubbers, capacitors, or diodes must be placed physically close to the device they are intended to protect. These protection devices must be routed with short traces to reduce inductance. For example, TI recommends a protection Schottky diode to address negative transients due to switching of inductive loads. TI recommends to add a ceramic decoupling capacitor (COUT) of 1 μF or greater between OUT and GND. These components must be physically close to the OUT pins. Care must be taken to minimize the loop area formed by the Schottky diode and bypass-capacitor connection, the OUT pin, and the GND pin of the IC.

The device has separate Vcc pin for powering itself and it can remain on with Vcc supply. illustrates the application at the output of DC/DC or flyback converter.

Transient Protection In the case of a short-circuit and overload current limit when the device interrupts current flow, the input inductance generates a positive voltage spike on the input, and the output inductance generates a negative voltage spike on the output. The peak amplitude of voltage spikes (transients) is dependent on the value of inductance in series to the input or output of the device. Such transients can exceed the absolute maximum ratings of the device if steps are not taken to address the issue. illustrates the transient protection circuit. Typical methods for addressing transients include: Minimize lead length and inductance into and out of the device. Use a large PCB GND plane. Connect a Schottky diode (D2) from the OUT pin ground to absorb negative spikes. The OUT pin has an absolute maximum rating of –1 V for negative transient spikes on output.

Layout Layout Guidelines High current-carrying power-path connections must be as short as possible and must be sized to carry at least twice the full-load current. The GND (PowerPAD) pin must be tied to the PCB ground plane at the terminal of the IC with the shortest possible trace. The PCB ground must be a copper plane or island on the board. TI recommends to have a separate ground plane island for the eFuse. This plane does not carry any high currents and serves as a quiet ground reference for all the critical analog signals of the eFuse. The device ground plane must be connected to the system power ground plane using a star connection. The optimal placement of the decoupling capacitor (CIN) is closest to the IN and GND pins of the device. Care must be taken to minimize the loop area formed by the bypass-capacitor connection, the IN pin, and the GND pin of the IC. Locate the following support components close to their connection pins: RILM or RPLM RIOCP CDLY CdVdT Resistors for OVP Connect the other end of the component to the GND pin of the device with shortest trace length. The trace routing for these components to the device must be as short as possible to reduce parasitic effects on the current limit, overcurrent blanking interval, and soft-start timing. Because the bias current on ILM pin directly controls the overcurrent protection behavior of the device, the PCB routing of this node must be kept away from any noisy (switching) signals. Protection devices such as TVS, snubbers, capacitors, or diodes must be placed physically close to the device they are intended to protect. These protection devices must be routed with short traces to reduce inductance. For example, TI recommends a protection Schottky diode to address negative transients due to switching of inductive loads. TI recommends to add a ceramic decoupling capacitor (COUT) of 1 μF or greater between OUT and GND. These components must be physically close to the OUT pins. Care must be taken to minimize the loop area formed by the Schottky diode and bypass-capacitor connection, the OUT pin, and the GND pin of the IC.

The TPS1641x is an integrated eFuse with accurate power limit or current limit. The device integrates an NFET with RON of 152 mΩ. TPS16410, TPS16411, TPS16414 and TPS16415 provide power limiting whereas the TPS16412, TPS16413, TPS16416 and TPS16417 provide current limiting. The TPS16410, TPS16411, TPS16414 and TPS16415 can provide 15-W accurate power limiting for low power circuit (LPCs) as per IEC60335 and UL60730 standards. TPS16410, TPS16411, TPS16412 and TPS16413 also provide IN to OUT short detection and its indication on FLT output. IN to OUT short detection eliminates the need of additional eFuse or power limiting circuit in case of IN to OUT short test for IEC60335, UL60730, and similar standards. FLT can be used as input for MCU or it can be used to drive an external PFET. TPS1641x devices also provide protection from adjacent pin short and pin short to GND faults. The TPS1641x device also provide configurable blanking time (IDLY or PDLY) and overcurrent protection (IOCP) for transient loads. Load such as motors need higher current for start-up. Blanking time is useful for providing higher current for start-up of loads such as motors. TPS1641x devices have overvoltage protection (OVP), overtemperature protection, and adjustable output slew rate control (dvdt). Vcc and FLT are rated up to 60 V and can provide protection up to 60 V with an external PFET. Functional Block Diagram Feature Description Enable and Shutdown Input (EN/SHDN) The TPS1641x devices include a enable and shutdown input. Keeping EN/SHDN low for a duration more than tLow_SHDN brings the device into low power shutdown mode, internal blocks of device are turned off, and the quiescent current of the device is reduced to IQSD from Vcc supply. While keeping EN/SHDN low for a duration less than tLow_SHDN, the device turns off the internal FET only and FET can be turned back on quickly. The device turns off the internal FET with a delay of tEN_OFF_dly as the enable pin is brought low. The internal FET can be enabled quickly with a delay of tEN_ON_dly when the device is not in shutdown. See the for VENR and VENF thresholds and the for tLow_SHDN, tEN_OFF_dly, and tEN_ON_dly timings. A PWM signal with low period less than tLow_SHDN can be provided on EN/SHDN pin of the device for fast turn-on and turn-off of internal FET. illustrates the EN/SHDN input in the TPS1641x devices. shows the start-up of the device with enable input. EN/SHDN in TPS1641x Devices Turn-On with Enable VIN = 12 V Overvoltage Protection (OVP) The TPS1641x implements overvoltage protection to protect the load from input overvoltage conditions. A resistor divider can be connected from the IN pin of device to configure the overvoltage protection setpoint. The device turns off the internal FET and asserts the FLT pin as the voltage at OVP pin goes above VOVPR, and as the OVP pin voltage falls below VOVPF, the internal FET is turned ON and FLT pin is de-asserted. See the table for VOVPF and VOVPR­ and for tOVP_entry_dly and tOVP_exit_dly timings for overvoltage protection input. illustrates the OVP input in TPS1641x devices. shows the overvoltage response. OVP Input in TPS1641x Overvoltage Protection Response for IN Voltage 12 V to 40 V Vcc and FLT pins of the device are rated up to 60 V, and the FLT pin can be used to drive an external PFET transistor and provide protection from 60-V overvoltage at input as shown in . Overvoltage (up to 60 V) Protection with External PFET To disable the overvoltage input, connect OVP to GND. If the OVP pin is left open, the device turns off the internal FET. Overvoltage Response with External PFET for IN Voltage from 12 V to 60 V Hot Plugin with External PFET for 60-V Input Output Slew Rate and Inrush Current Control (dVdt) During hot plug events or while trying to charge a large output capacitance, there can be a large inrush current. If the inrush current is not managed properly, it can damage the input connectors and cause the system power supply to droop leading to unexpected restarts elsewhere in the system. The inrush current during turn-on is directly proportional to the load capacitance and rising slew rate. can be used to find the output slew rate (SR) required to limit the inrush current (IINRUSH) for a given output capacitance (COUT). S R   =   I I N R U S H C O U T A capacitance can be added to the dVdt pin to control the rising slew rate and lower the inrush current during turn-on. The required CdVdt capacitance to produce a given slew rate can be calculated using . C d V d t   =   I d V d t   ×   G d V d t   S R The fastest output slew rate is achieved by leaving the dVdt pin open. If dVdt pin is connected to GND, the device will not power up the output. illustrates the output slew rate control in the TPS1641x devices. shows the output slew rate control response of the device. Output Slew Rate Control in the TPS1641x Output Slew Rate Control with VIN = 12 V, CdVdt = 150 nF, and COUT = 470 μF Active Current Limiting (ILIM) With the TPS16412, TPS16413, TPS16416, and TPS16417 B 20230421 Added new device variants no The TPS16412, TPS16413, TPS16416, and TPS16417 devices respond to output overcurrent or overload conditions by actively limiting the current. The devices first provide a blanking time configured by capacitance on the IDLY pin. During this blanking time, the device can provide a current up to IOCP value. After the end of this blanking time, the devices limit current to ILIM value. ILIM can be set by connecting resistor on ILIM pin. RILIM can be calculated by . I L I M =   0.984   A R I L I M     ×   10   k Ω If the output current exceeds IOCP, the device goes into current limiting. During current limiting, if the output current goes below ILIM (IOUT < ILIM), the device resets the IDLY timer and restarts IDLY timer when IOUT > ILIM. illustrates the current limiting behavior for IOUT < IOCP and for IOCP ≤ IOUT < Ifast-trip. During current limiting, if the output current goes below ILIM (IOUT < ILIM), the device resets the IDLY timer and restarts the IDLY timer when IOUT > ILIM. Current Limiting for IOUT < IOCP IOCP ≤ IOUT < Ifast-trip During the current limiting, the device dissipates a power of (VIN – VOUT) × IOUT and the device gets heated up. If the junction temperature of device reaches thermal shutdown temperature (TTSD), the device turns off the internal FET. If the device does not go into thermal shutdown, the internal FET is turned off after a duration of tILIM-DUR. After the internal FET is turned off, the TPS16412 and TPS16416 auto-retry while the TPS16413 and TPS16417 latch off. If ILIM pin is connected to GND or left open, the device turns-off the internal FET. If the IDLY pin is left open or connected to GND, device provides tILIM-DUR = 155 ms unless the device enters thermal shutdown. summarizes the device behavior for different output currents. Current Limiting and Overload Protection With TPS16412, TPS16413, TPS16416, and TPS16417 Output Current (IOUT) Device Response IOUT < ILIM The device provides current up to ILIM. ILIM ≤ IOUT < IOCP The device provides current up to IOCP for a duration of IDLY and then limits current to ILIM for a maximum duration of tILIM-DUR. IOCP ≤ IOUT < Ifast-trip The device limits current to ILIM for a maximum duration of tILIM-DUR. Ifast-trip ≤ IOUT < ISCP The device turns off the internal FET after a delay of tfast-trip. ISCP ≤ IOUT The device turns off the internal FET after a delay of tSCP_dly. Active Power Limiting (PLIM) With the TPS16410, TPS16411, TPS16414, and TPS16415 B 20230421 Added new device variants no The TPS16410, TPS16411, TPS16414, and TPS16415 devices respond to output overcurrent or overload conditions by actively limiting the output power. The devices first provide a blanking time configured by capacitance on PDLY pin. During this blanking time, the device can provide a current up to IOCP value. After the end of this blanking time, the devices limit power to PLIM value. Power limit can be set by connecting a resistor on the PLIM pin. During power limiting, if the output power goes below PLIM (POUT < PLIM), the device resets the PDLY timer and restarts the PDLY timer when POUT > PLIM. Use to calculate the value of resistor for power limiting. The device is rated for 1.8-A continuous current, TI recommends to set PLIM < VIN × 1.8 A and PLIM < 0.9 × VOUT × IOCP P L I M =   13.82   W 95.3   k Ω   ×   R P L I M illustrates the power limiting in the TPS16410 and TPS16411 devices for IOUT < IOCP and IOCP ≤ IOUT < Ifast-trip. Power Limiting (IOUT < IOCP) Power Limiting (IOCP ≤ IOUT < Ifast-trip) During power limiting, the device dissipates a power of (VIN – VOUT) × IOUT and the device gets heated up. If the junction temperature of device reaches thermal shutdown temperature (TTSD), the device turns off the internal FET. If the device does not go into thermal shutdown, the internal FET is turned off after a duration of tPLIM-DUR. After the internal FET is turned off, the TPS16410 and TPS16414 devices auto-retry while the TPS16411 and TPS16415 device latch off. If PLIM is connected to GND or left open, the device turns-off the internal FET. If the PDLY pin is left open or connected to GND, device provides tPLIM-DUR = 155 ms unless the device enters thermal shutdown. summarizes the device behavior for different output power and current. Power Limiting and Overload Response in TPS16410, TPS16411, TPS16414, and TPS16415 Devices Output Power (POUT) or Output Current (IOUT) Device Response POUT < PLIM The device provides power up to PLIM. PLIM ≤ POUT and IOUT < IOCP The device provides current up to IOCP for a duration of PDLY and then limits power to PLIM for a maximum duration of tPLIM-DUR. IOCP ≤ IOUT < Ifast-trip The device limits current to PLIM for a maximum duration of tPLIM-DUR. Ifast-trip ≤ IOUT < ISCP The device turns off the internal FET after a delay of tfast-trip. ISCP ≤ IOUT The device turns off the internal FET after a delay of tSCP_dly. Internal Current Limit for the TPS16410 and TPS16411 B 20230421 Added new device variants no In power limiting devices, there is an internal current limit. If during power up, the output current exceeds overcurrent protection setpoint (IOCP), these devices limit current to 0.81 × IOCP. TPS16410, TPS16411, TPS16414, and TPS16415 devices also limit the output current if PLIM is set to more than (VOUT × IOCP) and IOUT exceeds IOCP. Overcurrent Protection (IOCP) and Blanking Time (IDLY or PDLY) for Transient Loads In TPS1641x devices, the overcurrent protection set-point can be configured by connecting a resistor on IOCP pin. The resistor value for overcurrent can be calculated by #GUID-CEE5453C-3447-4C14-B02F-0B8783EC71CF/GUID-A9DDCAA1-1BA5-4DF1-B822-A1084D0ABB08. I O C P =   2.25   A R I O C P     ×   7.32   k Ω If the IOCP pin is left open or connected to GND, the device turns off the internal FET. The devices also provide blanking time for overload or overcurrent events. This blanking time can be configured by connecting a capacitor on IDLY or PDLY, and the blanking time can be calculated by #GUID-CEE5453C-3447-4C14-B02F-0B8783EC71CF/GUID-7B6743B8-5B89-4D39-B409-D5561E258CFF. If IDLY/PDLY pin is left open or connected to GND, device disables the blanking time and directly goes into power or current limiting.

When an output short-circuit is detected and output current reaches ISCP level, the device turns off the internal FET after a delay of tSCP_dly. In case of fast input transients, the current through internal FET rises rapidly, but these transients can lead to false turn-off of internal FET due to excessive flow of current through internal FET. To prevent false tripping during these input transients, the device includes fast-trip comparator, which turns off the internal FET if the output current exceeds Ifast-trip for a duration of tfast-trip. shows the short-circuit response of the device. Short-Circuit Response with VIN = 12 V Analog Load Current Monitor (IMON) on the IOCP Pin The device allows the system to monitor the output load current accurately by providing an analog current on the IOCP/IMON pin, which is proportional to the current through the FET. The resistor on IOCP/IMON pin converts this current into voltage and this voltage can be used for monitoring the output current.

Keeping EN/SHDN low for a duration more than tLow_SHDN brings the device into low power shutdown mode, internal blocks of device are turned off, and the quiescent current of the device is reduced to IQSD from Vcc supply. While keeping EN/SHDN low for a duration less than tLow_SHDN, the device turns off the internal FET only and FET can be turned back on quickly. The device turns off the internal FET with a delay of tEN_OFF_dly as the enable pin is brought low.

A resistor divider can be connected from the IN pin of device to configure the overvoltage protection setpoint. The device turns off the internal FET and asserts the FLT pin as the voltage at OVP pin goes above VOVPR, and as the OVP pin voltage falls below VOVPF, the internal FET is turned ON and FLT pin is de-asserted. See the table for VOVPF and VOVPR­ and for tOVP_entry_dly and tOVP_exit_dly timings for overvoltage protection input. illustrates the OVP input in TPS1641x devices. shows the overvoltage response.

During current limiting, if the output current goes below ILIM (IOUT < ILIM), the device resets the IDLY timer and restarts IDLY timer when IOUT > ILIM. illustrates the current limiting behavior for IOUT < IOCP and for IOCP ≤ IOUT < Ifast-trip. During current limiting, if the output current goes below ILIM (IOUT < ILIM), the device resets the IDLY timer and restarts the IDLY timer when IOUT > ILIM. Current Limiting for IOUT < IOCP IOCP ≤ IOUT < Ifast-trip During the current limiting, the device dissipates a power of (VIN – VOUT) × IOUT and the device gets heated up. If the junction temperature of device reaches thermal shutdown temperature (TTSD), the device turns off the internal FET.

Active Power Limiting (PLIM) With the TPS16410, TPS16411, TPS16414, and TPS16415 B 20230421 Added new device variants no The TPS16410, TPS16411, TPS16414, and TPS16415 devices respond to output overcurrent or overload conditions by actively limiting the output power. The devices first provide a blanking time configured by capacitance on PDLY pin. During this blanking time, the device can provide a current up to IOCP value. After the end of this blanking time, the devices limit power to PLIM value. Power limit can be set by connecting a resistor on the PLIM pin.

If the junction temperature of device reaches thermal shutdown temperature (TTSD), the device turns off the internal FET. If the device does not go into thermal shutdown, the internal FET is turned off after a duration of tPLIM-DUR. After the internal FET is turned off, the TPS16410 and TPS16414 devices auto-retry while the TPS16411 and TPS16415 device latch off. If PLIM is connected to GND or left open, the device turns-off the internal FET.

Internal Current Limit for the TPS16410 and TPS16411 B 20230421 Added new device variants no In power limiting devices, there is an internal current limit. If during power up, the output current exceeds overcurrent protection setpoint (IOCP), these devices limit current to 0.81 × IOCP. TPS16410, TPS16411, TPS16414, and TPS16415 devices also limit the output current if PLIM is set to more than (VOUT × IOCP) and IOUT exceeds IOCP. Overcurrent Protection (IOCP) and Blanking Time (IDLY or PDLY) for Transient Loads In TPS1641x devices, the overcurrent protection set-point can be configured by connecting a resistor on IOCP pin. The resistor value for overcurrent can be calculated by #GUID-CEE5453C-3447-4C14-B02F-0B8783EC71CF/GUID-A9DDCAA1-1BA5-4DF1-B822-A1084D0ABB08.

When an output short-circuit is detected and output current reaches ISCP level, the device turns off the internal FET after a delay of tSCP_dly. In case of fast input transients, the current through internal FET rises rapidly, but these transients can lead to false turn-off of internal FET due to excessive flow of current through internal FET. To prevent false tripping during these input transients, the device includes fast-trip comparator, which turns off the internal FET if the output current exceeds Ifast-trip for a duration of tfast-trip. shows the short-circuit response of the device. Short-Circuit Response with VIN = 12 V Analog Load Current Monitor (IMON) on the IOCP Pin The device allows the system to monitor the output load current accurately by providing an analog current on the IOCP/IMON pin, which is proportional to the current through the FET. The resistor on IOCP/IMON pin converts this current into voltage and this voltage can be used for monitoring the output current. Output current can be calculated from voltage at IOCP/IMON pin by using #GUID-743F91F2-76AD-49F8-AE6D-FF0DB411EC6F/GUID-EA44A692-6D23-44A1-BE93-D8E476299700.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. Application Information TPS1641x devices include power limiting or current limiting for a low power circuit (as per IEC60335 and UL60730 standards) in appliances, HVAC actuators, and medical equipment. TPS1641x devices also have IN to OUT short detection for internal FET for IN-OUT short testing during IEC60335 or UL60730 certifications. The TPS16410 and TPS16411 have an accurate power limiting feature while the TPS16412 and TPS16413 have an accurate current limiting feature. For transient current required for start-up of motors or actuators, TPS1641x devices have a configurable overcurrent protection threshold (IOCP) and configurable blanking time (IDLY/PDLY). For start-up with big capacitance (< 1 mF) on output, the TPS1641x include dVdT feature to control the output slew rate and limiting the inrush current during power up. The output current can be monitored from IOCP or IMON pin, by sensing the voltage on this pin. Typical Application: 15-W Power Limiting for Low Power Circuits (LPCs) The TPS16410 and TPS16411 can be used for 15-W power limiting for low-power circuits in IEC60335 and UL60730 standards. The output power limit can be configured by a resistor on the PLIM pin. provides a typical application circuit for 15-W power limiting. 15-W Power Limiting for Low-Power Circuits Design Requirements Design Parameters Parameter Value VIN 18 V to 32 V POUT ≤ 15 W Overcurrent protection 1 A Output capacitance (COUT) 470 μF IINRUSH ≤ 350 mA Blanking time for transients (PDLY) 6.5 ms Detailed Design Procedure Setting Overvoltage Setpoints Input overvoltage protection setpoints can be set by connecting resistors (R1, R2) from the IN pin to OVP pin. The value of resistors can be calculated using #GUID-E1DF5068-A0C0-4FF5-8AE4-A3F3DEF92878/EQUATION-BLOCK_X4M_ZF3_STB and #GUID-E1DF5068-A0C0-4FF5-8AE4-A3F3DEF92878/EQUATION-BLOCK_TZV_ZF3_STB. To set the OVP rising setpoint to 32 V, R1 = 1 MΩ and R2 = 47 kΩ are selected.

To calculate the value of this resistor (R4), use . For IOCP = 1 A, R4 is selected as 16.2 kΩ. Setting the Output Power Limit For setting the output power limit, a resistor (R3) is required on the PLIM pin. To calculate the value of power limit, use. To keep output power limit ≤ 15 W, R3 was selected as 95.3 kΩ. Monitoring the Output Current The output current can be monitored on IOCP or IMON by reading the voltage on this pin. The output current can be calculated using . Limiting the Inrush Current and Setting the Output Slew Rate For charging the large capacitors on output, the output slew rate can be controlled by using a capacitor on dVdt pin. The value of inrush current can be estimated by #GUID-D88A6004-2EF8-434E-BA27-D6801E7DF9FF/GUID-F96B89FD-DCBD-4096-A701-579C6434AF9D.

For additional protection, the device has a fault pin and it is asserted in case of overvoltage, overcurrent or overpower, IN-short detection and thermal shutdown events. The fault can be used to turn-off the DC/DC converter or flyback converter providing the power to input of TPS1641 for the load. The device has separate Vcc pin for powering itself and it can remain on with Vcc supply. illustrates the application at the output of DC/DC or flyback converter. Accurate Power or Current Limiting at the Output of DC/DC or Flyback Converter Best Design Practices Use CIN ≥ 10 nF for decoupling Vcc and IN pins. Do not leave the OVP, PLIM/ILIM, and IOCP/IMON pins open or floating. Connect the PowerPAD of the device to GND on the PCB. Do not connect the EN/SHDN pin to voltage more than 5 V. Power Supply Recommendations Use 4.5 V ≤ VIN ≤ 40 V for the TPS16410 and TPS16411. Use 2.7 V ≤ VIN ≤ 40 V for the TPS16412 and TPS16413. Use VIN ≤ VCC ≤ 60 V. Pull up FLT with voltage ≤ 60 V. Use a pullup resistor to keep current into the FLT pin < 3 mA. Transient Protection In the case of a short-circuit and overload current limit when the device interrupts current flow, the input inductance generates a positive voltage spike on the input, and the output inductance generates a negative voltage spike on the output. The peak amplitude of voltage spikes (transients) is dependent on the value of inductance in series to the input or output of the device. Such transients can exceed the absolute maximum ratings of the device if steps are not taken to address the issue. illustrates the transient protection circuit. Typical methods for addressing transients include: Minimize lead length and inductance into and out of the device. Use a large PCB GND plane. Connect a Schottky diode (D2) from the OUT pin ground to absorb negative spikes. The OUT pin has an absolute maximum rating of –1 V for negative transient spikes on output. Connect a low-ESR capacitor larger than 1 μF at the OUT pin very close to the device. Use a low-value ceramic capacitor CIN = 0.1 μF to absorb the energy and dampen the transients. The approximate value of input capacitance can be estimated with . V I N - S P I K E = V I N +   I L O A D   ×   L I N   C I N Some applications require additional Transient Voltage Suppressor (TVS) to keep transients below the absolute maximum rating of the device. A TVS can help to absorb the excessive energy dump and prevent it from creating very fast transient voltages on the input of the device. Use a suitable TVS to clamp the transient voltage below the absolute maximum rating of the device. Transient Protection with TPS1641x TVS D1* and Schottky D2* are optional diodes for transient protection on the input and output. Layout Layout Guidelines High current-carrying power-path connections must be as short as possible and must be sized to carry at least twice the full-load current. The GND (PowerPAD) pin must be tied to the PCB ground plane at the terminal of the IC with the shortest possible trace. The PCB ground must be a copper plane or island on the board. TI recommends to have a separate ground plane island for the eFuse. This plane does not carry any high currents and serves as a quiet ground reference for all the critical analog signals of the eFuse. The device ground plane must be connected to the system power ground plane using a star connection. The optimal placement of the decoupling capacitor (CIN) is closest to the IN and GND pins of the device. Care must be taken to minimize the loop area formed by the bypass-capacitor connection, the IN pin, and the GND pin of the IC. Locate the following support components close to their connection pins: RILM or RPLM RIOCP CDLY CdVdT Resistors for OVP Connect the other end of the component to the GND pin of the device with shortest trace length. The trace routing for these components to the device must be as short as possible to reduce parasitic effects on the current limit, overcurrent blanking interval, and soft-start timing. Because the bias current on ILM pin directly controls the overcurrent protection behavior of the device, the PCB routing of this node must be kept away from any noisy (switching) signals. Protection devices such as TVS, snubbers, capacitors, or diodes must be placed physically close to the device they are intended to protect. These protection devices must be routed with short traces to reduce inductance. For example, TI recommends a protection Schottky diode to address negative transients due to switching of inductive loads. TI recommends to add a ceramic decoupling capacitor (COUT) of 1 μF or greater between OUT and GND. These components must be physically close to the OUT pins. Care must be taken to minimize the loop area formed by the Schottky diode and bypass-capacitor connection, the OUT pin, and the GND pin of the IC.

The device has separate Vcc pin for powering itself and it can remain on with Vcc supply. illustrates the application at the output of DC/DC or flyback converter.

Transient Protection In the case of a short-circuit and overload current limit when the device interrupts current flow, the input inductance generates a positive voltage spike on the input, and the output inductance generates a negative voltage spike on the output. The peak amplitude of voltage spikes (transients) is dependent on the value of inductance in series to the input or output of the device. Such transients can exceed the absolute maximum ratings of the device if steps are not taken to address the issue. illustrates the transient protection circuit. Typical methods for addressing transients include: Minimize lead length and inductance into and out of the device. Use a large PCB GND plane.

Layout Layout Guidelines High current-carrying power-path connections must be as short as possible and must be sized to carry at least twice the full-load current. The GND (PowerPAD) pin must be tied to the PCB ground plane at the terminal of the IC with the shortest possible trace. The PCB ground must be a copper plane or island on the board. TI recommends to have a separate ground plane island for the eFuse. This plane does not carry any high currents and serves as a quiet ground reference for all the critical analog signals of the eFuse. The device ground plane must be connected to the system power ground plane using a star connection. The optimal placement of the decoupling capacitor (CIN) is closest to the IN and GND pins of the device. Care must be taken to minimize the loop area formed by the bypass-capacitor connection, the IN pin, and the GND pin of the IC. Locate the following support components close to their connection pins: RILM or RPLM RIOCP CDLY CdVdT Resistors for OVP Connect the other end of the component to the GND pin of the device with shortest trace length. The trace routing for these components to the device must be as short as possible to reduce parasitic effects on the current limit, overcurrent blanking interval, and soft-start timing. Because the bias current on ILM pin directly controls the overcurrent protection behavior of the device, the PCB routing of this node must be kept away from any noisy (switching) signals. Protection devices such as TVS, snubbers, capacitors, or diodes must be placed physically close to the device they are intended to protect. These protection devices must be routed with short traces to reduce inductance. For example, TI recommends a protection Schottky diode to address negative transients due to switching of inductive loads. TI recommends to add a ceramic decoupling capacitor (COUT) of 1 μF or greater between OUT and GND. These components must be physically close to the OUT pins. Care must be taken to minimize the loop area formed by the Schottky diode and bypass-capacitor connection, the OUT pin, and the GND pin of the IC.
