MD7033

Shanghai Mingda Microelectronics · Monitors & Reset Circuits · SOT-23-5L

MD7033 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 Active-low NMOS open-drain detector output that goes low when VDD falls below the 3.3V detect voltage, sinking at least 2 mA at VOUT=0.2V (VDD=3.1V), with output current limited to 10mA and output voltage to VSS-0.3V to VDD+0.3V.
2 VDD power_in Positive supply input and monitored voltage, with an operating range of 1.5V to 15V and an absolute maximum of -0.3V to 18V.
3 GND power_in Ground reference (VSS) for the detector.
4 NC unconnected No-connect pin, labeled NC on the SOT23-5 pin assignment drawing.
5 NC unconnected No-connect pin, labeled NC on the SOT23-5 pin assignment drawing.

CAD (KiCad official)

  • Symbol: MD7033
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5L (KiCad packages3D, STEP)
  • 3D model files: md7033-etched.step / md7033-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); md7033.step / md7033.glb are the bare package body.

Provenance
