MT8311AT 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 stated operating range of 3.8 V to 60 V, an absolute maximum VCC of 65 V, and reverse battery protection down to -20 V. |
| 2 | OUT | output | Open-drain output that turns on (Low) when B exceeds BOP, with VDSON max 0.4 V at 15 mA, continuous output current max 40 mA, output leakage max 10 µA at VOUT = 24 V, and output current limiting protection. |
| 3 | GND | power_in | Ground reference pin for the device. |
