AP2141DWG-7 from Diodes Incorporated, in a SOT-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 | OUT | power_out | Voltage output pin; all OUT pins must be tied together externally, and the output is current-limited to about 0.8 A typical (0.6 A to 1.0 A) with reverse-current blocking when the switch is disabled. |
| 2 | GND | power_in | Ground pin for the device; the datasheet gives no separate exposed-pad connection for the SOT25 package. |
| 3 | FLG | output | Over-current and over-temperature fault report; open-drain output that goes active low when triggered, after a 7 ms (typ) deglitch time, and its FET on-resistance is 20 Ω typical (40 Ω max at 10 mA). |
| 4 | EN | input | Active-low enable input on the AP2141D (switch on when pulled low); the logic-low input must be 0 V to 0.8 V and the logic-high input must be 2.0 V up to VIN. |
| 5 | IN | power_in | Voltage input pin with a 2.7 V to 5.5 V operating range (6.5 V absolute maximum); all IN pins must be tied together externally. |
