MD7020

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

MD7020 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 Detector output, N-channel open drain and active low for MD7020, sinking min 1 mA (typ 2 mA) at VOUT=0.2V, with output current limited to 10mA absolute maximum.
2 VDD power_in Positive supply and detect-voltage sense input, with 1.5V to 15V operating range for MD7020 (2.0V detect threshold, 0.100V typ hysteresis) and 18V absolute maximum.
3 GND power_in Ground (VSS) reference for the supply and output.
4 NC unconnected No connection pin on the SOT23-5 package, shown at the top right of the package drawing.
5 NC unconnected No connection pin on the SOT23-5 package, shown at the top left of the package drawing.
