# MT8512AT

**Magn Tek** · Hall Sensor · SOT-23

MT8512AT from Magn Tek, in a SOT-23. 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 | Positive supply voltage input. Operating range 3.0V to 24V, absolute maximum 30V. Reverse battery protection to -16V. Typical bypass 100nF close to pin. |
| 2 | Out | output | Open-drain digital output. Pulled low (Vout=Low, Vdson<=0.4V at Iout=20mA) when magnetic flux density exceeds Bop; high-impedance (pull-up required) when below Brp. Max Iout 55mA, output voltage max 30V, leakage <=10uA. Recommended external pull-up RL 1kOhm to 10kOhm. |
| 3 | GND | power_in | Ground reference (0V). |

## CAD (KiCad official)

- Symbol: `MT8512AT`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `mt8512at-etched.step` / `mt8512at-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mt8512at.step` / `mt8512at.glb` are the bare package body.
