**Allegro MicroSystems LLC** · Hall Sensor · SOT-23W

A3214ELHLT-T 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 | VDD | power_in | Input power supply, 2.4 to 5.5 V operating range (6 V absolute max). Tie to GND with a bypass capacitor. |
| 2 | VOUT | output | Open-drain / MOSFET digital output signal. Latched Hall-switch output; rated for up to 6 V off voltage and 1 mA output current (V_OUT(ON) typ 100 mV at I_OUT = 1 mA). |
| 3 | GND | power_in | Ground reference for the device. |
