# AP22817AKAWT-7

**Diodes Incorporated** · Power Distribution Switches · TSOT-25

AP22817AKAWT-7 from Diodes Incorporated, in a TSOT-25. 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 | EN | input | Enable input for the AP22817A (active-high); the datasheet specifies VIH of 1.5 V minimum and VIL of 0.5 V maximum, and the pin should not be left floating. |
| 2 | GND | power_in | Ground pin of the circuitry. |
| 3 | FLG | output | Overcurrent and overtemperature fault report; open-drain flag that is active-low when triggered, after a nominal 6 ms deglitch. |
| 4 | IN | power_in | Voltage input pin; connect a 1 µF low-ESR capacitor to GND close to the IC. Operating input range is 2.7 V to 5.5 V. |
| 5 | OUT | power_out | Voltage output pin; connect a 0.1 µF bypass capacitor and a high-value capacitor to GND close to the IC (at least 10 µF in USB applications). |
