3 说明

DRV110 器件是一款面向电磁阀的 PWM 电流控制器。该器件旨在通过良好受控的波形来调节电流，从而减少功率损耗。电磁阀电流快速斜升，可确保正常打开阀门或继电器。最初上升后，电磁阀电流将保持峰值以确保正常运行；此后，电流降至较低的保持水平，以避免过热问题并减少功率损耗。

使用外部电容器设置峰值电流持续时间。可使用外部电阻器单独设置电流斜坡的峰值和保持水平以及 PWM 频率。如果相应参数的默认值适用于该应用，甚至无需使用外部设置电阻器。

DRV110 器件具有内部齐纳二极管，可将输入电压限制到 VZENER，适用于需要较高电源电压的 应用 。借助内部齐纳二极管，DRV110 允许通过整流器和限流电阻器由 120V 和 230V 交流电源供电。也可通过此方式调节高直流电压，例如 48V。

(1) In the 8-pin package, the HOLD pin is not bonded out. For this package, the HOLD mode is configured to default (internal) settings.

6 Specifications

6.1 Absolute Maximum Ratings

See (1) and (2)
MIN MAX UNIT
VIN Input voltage –0.3 20 V
Voltage on EN, STATUS, PEAK, HOLD, OSC, SENSE, KEEP –0.3 7 V
Voltage on OUT –0.3 20 V
TJ Operating junction temperature –40 150 °C
Tstg Storage temperature –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
Charged device model (CDM), per JEDEC specification JESD22-C101(2) ±500
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

6.3 Recommended Operating Conditions

–40°C ≤ TA ≤ 125°C (unless otherwise noted)
MIN NOM MAX UNIT
IQ Supply current (the device sinks additional current when VIN> VZENER(1)) 1 1.5 3 mA
VIN Voltage at the VIN pin(2)(3) (see Detailed Description) 6 V
VS Voltage directly from the supply before clamped by the Zener diode 6 330 V
CIN Input capacitor between VIN and GND(4) 1 4.7 µF
TA Operating ambient temperature –40 125 °C
(1) The device regulates the supply with an internal Zener diode. The device sinks up to 3 mA with the added supply current. See Equation 5 to find appropriate value for the RS resistor.
(2) The maximum input voltage of the device depends on the clamping voltage of the internal Zener diode, which changes over temperature. A current-limiting resistor is required to limit current to the Zener diode if the input voltage (VIN) is greater than VZENER. For more information on resistor sizing see the Detailed Description section and Application and Implementation section.
(3) For VS voltages less than VZENER, VIN = VS. For VS voltages greater than VZENER, VIN = VZENER.
(4) 4.7-µF input capacitor and full wave rectified 230-Vrms AC supply results in approximately 500-mV supply ripple.
