Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 IN Power Input supply voltage.
2 UVLO I Resistor programmable undervoltage lockout threshold setting input. An undervoltage event will open the internal FET. If the Undervoltage Lock Out function is not needed, the UVLO terminal must be connected to the IN terminal with atleast 1 MΩ resistor. UVLO pin is 5 V rated and this resistor limits the UVLO pin current to < 60 µA
3 OVP I Resistor programmable overvoltage protection threshold. An overvoltage event will open internal FET. In TPS26620, TPS26621, TPS26624, TPS26625 devices if over voltage protection feature is not to be used then connect OVP terminal to RTN. For overvoltage clamp response (TPS26622 and TPS26623 Only) connect OVP to RTN externally.
4 SHDN I Shutdown PIN. Pulling it low makes the device to enter into low power shutdown mode. Cycling SHDN low and then back high resets the device that has latched off (TPS26620, TPS26622, TPS26624 only) due to a fault condition.
5 RTN Reference ground for all internal voltages.
6 GND System Ground.
7 ILIM I/O A resistor from this pin to RTN sets the overload and short-circuit current limit. See the Overload and Short Circuit Protection section.
8 dVdT I/O A capacitor from this pin to RTN sets output voltage slew rate. See the Hot Plug-In and In-Rush Current Control section.
9 FLT O Fault event indicator. It is an open drain output. If unused, leave floating.
10 OUT Power Output Voltage.
PowerPadTM Connect PowerPad to RTN plane for heat sinking. Do not use PowerPad as the only electrical connection to RTN.
