MD7043

Shanghai Mingda Microelectronics · Monitors & Reset Circuits · SOT-89-3

MD7043 from Shanghai Mingda Microelectronics, in a SOT-89-3. 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 (NMOS open drain, active low, unless the C suffix selects CMOS output); output current is limited to 10mA and output voltage to VSS-0.3V to VDD+0.3V.
2 VDD power_in Supply input; operating voltage is 1.5V to 15V for most MD70XX parts and absolute maximum supply voltage is -0.3V to 18V.
3 GND power_in Ground (VSS) reference pin for the voltage detector.

CAD (KiCad official)

  • Symbol: MD7043
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: md7043-etched.step / md7043-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); md7043.step / md7043.glb are the bare package body.
