MD6127C23 from Shanghai Mingda Microelectronics, in a SOT-23-3L. 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 | VOUT | output | Voltage detection output; NMOS open-drain on the N variant or CMOS push-pull on the C variant, switching to VSS below the detection voltage and to VDD after the fixed 200 ms delay on release. |
| 2 | VSS | power_in | Ground pin, the reference for the detection voltage and the output low level. |
| 3 | VDD | power_in | Detection voltage input with an operating voltage range of 1 V to 12 V and an absolute maximum VDD-VSS of 15 V. |
