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. |
