MT3151AT-EN from Magn Tek, in a SOT-23. 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 | Vcc | power_in | Supply pin for the Hall switch, operating range 3.0 V to 24 V (absolute maximum supply 30 V, reverse battery protection to -16 V). |
| 2 | OUT | output | Open-drain output that turns ON (Low) when B exceeds BOP and OFF (High) when B falls below BRP; continuous output current is limited to 55 mA absolute maximum and output voltage is rated to 30 V. |
| 3 | GND | power_in | Ground reference pin for the device. |
