MD7030

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

MD7030 from Shanghai Mingda Microelectronics, in a SOT-23-3L. 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 VOUT output NMOS open-drain detector output (normally open, active low). Pulls to VSS when VDD falls below VDET (3.0V typ.); requires an external pull-up to VDD or a separate rail. Sink capability typically 2.7mA at VOUT=0.2V (guaranteed 2-4mA range). Not valid while VDD is below the minimum operating voltage.
2 GND power_in Ground / VSS reference (0 V). Connect to system ground.
3 VDD power_in Positive supply and monitored input. Operating range 1.5V to 15V (absolute max 18V, -0.3V to 18V). Detection threshold VDET is applied to this pin; typical no-load supply current 1.2µA.
