A3214LLHLT-T
Allegro MicroSystems LLC · Linear Hall Sensors · SOT-23W
A3214LLHLT-T 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 | VDD | power_in | Input power supply; tie to GND with a bypass capacitor, with operating supply voltage range 2.4 V to 5.5 V and absolute maximum supply voltage of 6 V. |
| 2 | VOUT | output | Output signal; the output switches low (turns on) when the magnetic flux exceeds the operate point and can sink up to 1 mA, with absolute maximum output off voltage of 6 V. |
| 3 | GND | power_in | Ground reference for the device; a bypass capacitor should be connected between supply and ground close to the Hall element. |

Materials and finish
As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).
| Part | Material | Colour / plating | Datasheet says | Page |
|---|---|---|---|---|
