Magn Tek · Hall Switches · SOT-23
MT3401AT-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 | VS | power_in | Supply pin with a stated operating range of 2.8 V to 24 V, an absolute maximum of 27 V, and a reverse battery voltage limit of -27 V. |
| 2 | OUT | output | Open-drain output that turns on (Low) when B exceeds BOP and turns off (High) when B falls below BRP, with a maximum voltage of 27 V and continuous output current of 50 mA, and over-current protection (IOCP typically 50 mA). |
| 3 | GND | power_in | Ground reference pin; all voltages in the absolute maximum ratings are referenced to GND. |
