MD7019

Shanghai Mingda Microelectronics · Monitors & Reset Circuits · SOT-23-3L

MD7019 from Shanghai Mingda Microelectronics, in a SOT-23-3L. 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 N-channel open-drain, active-low detector output (MD7019 has no C suffix) that sinks min 1 mA (typ 2 mA) at VOUT=0.2V, with absolute maximum output current 10mA and a 1.9V detect threshold.
2 GND power_in Ground (VSS) reference for the detector.
3 VDD power_in Supply input and monitored voltage, with operating range 1.5V to 15V for MD7019 and absolute maximum -0.3V to 18V.

CAD (KiCad official)

  • Symbol: MD7019
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: md7019-etched.step / md7019-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); md7019.step / md7019.glb are the bare package body.
