APS12202LLHALT

Allegro MicroSystems, LLC · Linear Hall Sensors · SOT-23W

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.
