MT8512ET 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 with a 3.0 V to 24 V operating range; the datasheet also specifies -16 V reverse battery protection and a 30 V absolute maximum supply voltage. |
| 2 | OUT | output | Open-drain output that is low when B is above BOP and high when B is below BRP, with continuous output current limited to 55 mA absolute maximum and output voltage up to 30 V. |
| 3 | GND | power_in | Ground reference pin for the device. |
