APS12202LLHALT from Allegro MicroSystems, LLC, in a SOT-23W. 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 | VCC | power_in | Power supply input operating from 3.0 to 24 V (absolute maximum 26.5 V, reverse battery -20 V); an external bypass capacitor close to the device is strongly recommended. |
| 2 | OUT | output | Short-circuit protected open-drain output that sinks up to 25 mA continuous (current limit 30 to 60 mA) and withstands up to 26 V in the off state. |
| 3 | GND | power_in | Ground reference pin. |
