MD6127C46 from Shanghai Mingda Microelectronics, in a SOT-23-5. 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 | DS | input | Delay time switching pin; must be fixed at low or high level (high level shortens the delay time), with VSH min 1.0 V and VSL max 0.3 V at VDD=6.0 V. |
| 2 | VSS | power_in | Ground pin. |
| 3 | NC | unconnected | No connection. |
| 4 | VOUT | output | Voltage detection output (NMOS open-drain or CMOS push-pull), output current up to 50 mA absolute maximum. |
| 5 | VDD | power_in | Detection voltage input and supply pin, operating range 1 V to 12 V, absolute maximum 15 V. |
