MIC803-30D4VM3-TR

Microchip Tech · Monitors & Reset Circuits · SOT-23

MIC803-30D4VM3-TR from Microchip Tech, in a SOT-23. 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 GND power_in Ground.
2 /RESET output Open-drain active-low reset output that goes low if VCC falls below the reset threshold (VTH) and stays asserted for one timeout period after VCC exceeds VTH; needs a pull-up resistor limited to 5.5V and remains valid with VCC as low as 1.0V.
3 VCC power_in Power supply input and monitored voltage, operating range 1.0V to 5.5V (absolute maximum 6.0V).
