MD6127C26 from Shanghai Mingda Microelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DS input Delay time ON/OFF switching control input. Must be tied to a fixed logic level: low selects the full internal delay tD1 (typ. 200 ms); high shortens the delay to (tD1 - tD2) since output is taken from a mid-point of the counter chain. VSH ≥ 1.0 V, VSL ≤ 0.3 V at VDD = 6.0 V.
2 VSS power_in Ground reference terminal.
3 NC unconnected No internal connection. Leave floating or tie to any convenient net.
4 VOUT output Voltage detection output. Asserts low when VDD falls below -VDET (2.6 V typ. for C26); after VDD rises above +VDET, the output is released high following the internal delay tD. In NMOS open-drain variants a pull-up resistor (e.g. 100 kΩ) to VDD is required; CMOS variant drives push-pull. Output current up to 50 mA absolute max.
5 VDD power_in Supply and sense input. Operating range 1 V to 12 V (15 V absolute max VDD-VSS). This is the voltage monitored against the internal 2.6 V detection threshold.
