MCP120T-315I

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

MCP120T-315I from Microchip Tech, in a SOT-23-3. 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 RST output Active-low open-drain RESET output (MCP120, no internal pull-up) that asserts whenever VDD is below the trip point and is held for 350 ms typical (150 ms min, 700 ms max) after VDD rises above it, with VOL max 0.4 V at IOL = 3.2 mA for the -315 trip option.
2 VDD power_in Supply voltage input and monitored voltage, operating range 1.0 V to 5.5V (absolute max 7.0V), with a 0.1 µF bypass capacitor recommended close to the pin.
3 VSS power_in Ground reference for the device.
