AP2161SG-13

Diodes Incorporated · AC-DC Controllers & Regulators · SOIC-8

AP2161SG-13 from Diodes Incorporated, in a SOIC-8. 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 GND power_in Ground pin of the switch.
2 IN power_in Voltage input pin (2.7V to 5.5V operating range); all IN pins must be tied together externally.
3 IN power_in Voltage input pin (2.7V to 5.5V operating range); all IN pins must be tied together externally.
4 EN input Enable input, active low for AP2161 (AP2171 is active high); VIH min 2.0V, VIL max 0.8V.
5 FLG output Open-drain overcurrent and over-temperature fault flag, active low when triggered, with 7ms typical deglitch blanking time.
6 OUT power_out Voltage output pin with 1.5A typical current limit; all OUT pins must be tied together externally.
7 OUT power_out Voltage output pin with 1.5A typical current limit; all OUT pins must be tied together externally.
8 NC unconnected No internal connection; datasheet recommends tying it to the OUT pins.
