MCP111T-450E

Microchip · Supervisor and Reset ICs · SOT-23

MCP111T-450E from Microchip, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT output Active-low, open-drain reset output. Pulls low when VDD is below the 4.38 V trip point and releases (goes high-impedance) when VDD rises above the threshold plus hysteresis. Requires an external pull-up resistor (typ. 100 kΩ); VOL ≤ 0.4 V at IOL = 500 µA; open-drain leakage IOD ≈ 0.1 µA.
2 VSS power_in Ground / negative supply reference.
3 VDD power_in Positive supply and monitored voltage input. Operating range 1.0 V to 5.5 V, absolute maximum 7.0 V. Detector compares this rail against the internal 4.38 V (450 option) trip threshold. Operating current IDD ≤ 1.75 µA.
