A3212ELHLT-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 | VCC | power_in | Supply voltage input. Operating range 2.5 V to 3.5 V (absolute max 4.0 V). Bypass with a ceramic capacitor to GND close to the pin. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | OUTPUT | output | Open-drain Hall-switch output. Pulled low when the magnetic flux density exceeds the operate point (BOP); high-impedance (requires external pull-up) when below the release point (BRP). |
