AP2171DWG-7

Diodes Incorporated · Power Distribution Switches · SOT-23-5

AP2171DWG-7 from Diodes Incorporated, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT power_out Voltage output pin of the power switch; the datasheet requires all OUT pins to be tied together externally, and VOUT is rated up to VIN + 0.3 V.
2 GND power_in Ground pin of the device.
3 FLG output Open-drain over-current and over-temperature fault report output, active low when triggered; the EN/FLG voltage absolute maximum is 6.5 V.
4 EN input Enable input, active high on the AP2171D; VIL is 0.8 V maximum and VIH is 2 V minimum over VIN = 2.7 V to 5.5 V, with an absolute maximum of 6.5 V.
5 IN power_in Voltage input pin that must be tied together with any other IN pins externally; the recommended input range is 2.7 V to 5.5 V and the absolute maximum is 6.5 V.
