AP2552W6-7

Diodes Incorporated · Power Distribution Switches · SOT-26

AP2552W6-7 from Diodes Incorporated, in a SOT-26. 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 IN power_in Input, connect a 0.1µF or greater ceramic capacitor from IN to GND as close to IC as possible.
2 GND power_in Ground, connect to external exposed pad.
3 EN input Enable input, logic low turns on power switch.
4 FAULT output Active-low open-drain output, asserted during over-current, over-temperature, or reverse-voltage conditions.
5 ILIM passive Use external resistor to set current-limit threshold; recommended 10kΩ ≦ RLIM ≦ 210kΩ.
6 OUT power_out Power switch output; the datasheet gives only 'Output' as its function for this pin.
