MCP120T-300I
Microchip Tech · Supervisor And Reset ICs · SOT-23
MCP120T-300I 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 | RST | output | Active-low open-drain RESET output (MCP120, no internal pull-up) asserted whenever VDD is below the trip point (2.85 V to 3.00 V for -300) and held for 350 ms typical (150 to 700 ms) after VDD rises above it. |
| 2 | VDD | power_in | Supply voltage and monitored input, operating range 1.0 V to 5.5 V, absolute maximum 7.0 V, with a 0.1 µF bypass capacitor recommended close to the pin. |
| 3 | VSS | power_in | Ground reference for the device. |
