AP22816AKWT-7

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

AP22816AKWT-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 FLG output Open-drain overcurrent and overtemperature fault flag, active-low when triggered, with a 6ms typical deglitch blanking time.
2 GND power_in Ground pin of the circuitry.
3 EN input Active-high enable input (AP22816A) with logic high at least 1.5V and logic low at most 0.5V; must not be left floating.
4 IN power_in Voltage input pin for 2.7V to 5.5V, connect a 1uF low-ESR capacitor to GND close to the IC.
5 OUT power_out Voltage output pin, connect a 0.1uF bypass capacitor and a high-value capacitor (at least 10uF in USB applications) to GND close to the IC.
