MCP131T-450E

Microchip Tech · Supervisor And Reset ICs · SOT-23-3

MCP131T-450E from Microchip Tech, in a SOT-23-3. 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 RST output Active-low reset output. Open-drain structure with an internal pull-up resistor (RPU ~95 kΩ typ.) to VDD. Asserted low while VDD < VTRIP (4.38V) and for tRPU (~120 ms typ.) after VDD rises above VTRIP. VOL ≤ 0.4V at IOL = 500 µA; maximum output current 10 mA. Absolute maximum on this pin is -0.6V to 13.5V w.r.t. VSS.
2 VDD power_in Positive supply input and the voltage being monitored. Operating range 1.0V to 5.5V; absolute maximum 7.0V. Rated VDD rise time ≤ 100V/µs. Typical steady-state supply current IDD < 1 µA (1.75 µA max) with the reset power-up timer inactive; up to ~90 µA while the tRPU timer is active. Input current absolute maximum 10 mA.
3 VSS power_in Device ground / negative supply reference. All voltages in the datasheet are specified with respect to VSS.
