AP22817BKEWT-7

Diodes Incorporated · Power Distribution Switches · TSOT-23-5

AP22817BKEWT-7 from Diodes Incorporated, in a TSOT-23-5. 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 OUT power_out Voltage output pin; connect a 0.1µF bypass capacitor and a high-value capacitor (at least 10µF in USB applications) to GND, close to the IC.
2 GND power_in Ground pin of the circuitry.
3 FLG output Overcurrent and overtemperature fault report; the open-drain flag is active-low when triggered (about 6 ms deglitch).
4 EN input Enable input; the AP22817B variant is active-low (VIL max 0.5 V, VIH min 1.5 V, and the pin should not be left floating).
5 IN power_in Voltage input pin, rated 2.7 V to 5.5 V; connect a 1µF low-ESR capacitor to GND, close to the IC.
