MD7033C

Shanghai Mingda Microelectronics · Supervisor And Reset ICs · SOT-23-5L

MD7033C from Shanghai Mingda Microelectronics, in a SOT-23-5L. 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; for the MD7033C it is a CMOS output (normally high, active low) that goes low when VDD falls below the 3.3V detect voltage (±3%), with output current limited to 10mA max.
2 VDD power_in Positive supply and voltage-sense input; operating voltage 1.5V to 15V for the MD7033 and absolute maximum -0.3V to 18V.
3 GND power_in Ground (VSS) reference for the detector.
4 NC unconnected No connection pin on the SOT23-5 package.
5 NC unconnected No connection pin on the SOT23-5 package.
