AP2401S-13

Diodes Incorporated · Power Distribution Switches · SO-8

AP2401S-13 from Diodes Incorporated, in a SO-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, the reference for all voltages on the device (datasheet absolute maximum ratings are referred to GND).
2 IN power_in Voltage input pin: connect a 0.1µF or larger ceramic capacitor from IN to GND as close as possible, and all IN pins must be tied together externally; VIN operating range is 2.7V to 5.5V.
3 IN power_in Voltage input pin: connect a 0.1µF or larger ceramic capacitor from IN to GND as close as possible, and all IN pins must be tied together externally; VIN operating range is 2.7V to 5.5V.
4 EN input Enable input, active low for the AP2401; logic low maximum 0.8V and logic high minimum 2V.
5 FLG output Over-temperature and over-current fault reporting with 7ms deglitch; active-low open-drain output that is disabled for 7ms after turn-on.
6 OUT power_out Voltage output pin; all OUT pins must be tied together externally.
7 OUT power_out Voltage output pin; all OUT pins must be tied together externally.
8 NC unconnected No internal connection; the datasheet recommends tying this pin to the OUT pins.
