MD7028

Shanghai Mingda Microelectronics · Supervisor And Reset ICs · SOT-89-3

MD7028 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, N-channel open drain (normally open, active low) for the MD70XX version, sinking up to a 10mA absolute maximum output current.
2 VDD power_in Positive supply input and monitored voltage, operating range up to 15V with an absolute maximum of 18V.
3 GND power_in Ground (VSS) reference pin for the supply and detector.

CAD (KiCad official)

  • Symbol: MD7028
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: md7028-etched.step / md7028-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); md7028.step / md7028.glb are the bare package body.
