MD7027C

Shanghai Mingda Microelectronics · Supervisor And Reset ICs · SOT-23-3L

MD7027C 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 Detector output, CMOS push-pull on the MD7027C (normally high, active low) that goes low when VDD falls below the 2.7V detect threshold; output current is rated up to 10mA.
2 GND power_in Ground reference (VSS) for the voltage detector.
3 VDD power_in Supply and sensed voltage input; operating voltage 1.5V to 15V for the MD7027 with an absolute maximum of 18V.
