MT1401ET-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; the datasheet gives a 2.8 V to 24 V operating range, with absolute maximum VCC of 27 V and reverse battery voltage of -27 V. |
| 2 | OUT | output | Open-drain output that turns Low when B exceeds BOP and High when B falls below BRP; output current is limited to 50 mA maximum and VOUT is rated to 27 V maximum. |
| 3 | GND | power_in | Ground reference pin. |
