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

APS11202LLHALT from Allegro MicroSystems LLC, in a SOT-23W. 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 | VCC | power_in | Power supply input. Operating range 3.0 to 24 V (absolute max 26.5 V). Reverse-battery protection to -20 V. A 0.1 uF bypass capacitor to GND close to the device is recommended. |
| 2 | OUT | output | Open-drain switch output, active low when south-polarity magnetic flux exceeds BOP (typ 35 G). Sinks up to 25 mA continuous with VOUT(SAT) typ 185 mV at 20 mA; internal current limit 30 to 60 mA. Requires an external pull-up resistor; output off voltage rated up to 26 V. |
| 3 | GND | power_in | Ground reference for the device. |
