AP2151AW-7 from Diodes Incorporated, in a SOT-25. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Switched voltage output pin. Sources up to 0.5A recommended continuous (0.8A typ. current limit) to the USB downstream load. For multi-OUT packages all OUT pins must be tied together; a bypass capacitor (0.1μF + bulk) at OUT is recommended. |
| 2 | GND | power_in | Device ground reference. |
| 3 | FLG | output | Open-drain fault flag output, active low when an over-current or over-temperature fault is detected. Blanking time (typ. 7ms) prevents false reporting during inrush; requires an external pull-up resistor (typ. 10kΩ) to VIN or logic rail. Internal FLG FET RDS(on) ~20Ω (max 40Ω) at IFLG=10mA. |
| 4 | EN | input | Active-high enable input for the AP2151A. VIL max 0.8V, VIH min 2V (up to VIN). Absolute-maximum enable voltage 6.5V. Drive high to turn the switch on, low to shut it down (typical shutdown current 0.5μA). |
| 5 | IN | power_in | Voltage input pin supplying the USB power switch. Operating range 2.7V to 5.5V (absolute max 6.5V). Bypass with 0.1μF close to the pin plus 10μF bulk. For multi-IN packages all IN pins must be tied together externally. |
