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. |
