MCP120T-450I

Microchip Tech · Monitors & Reset Circuits · SOT-23

MCP120T-450I 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 that asserts whenever VDD is below the trip point and is held for 350 ms (typ) after VDD rises above it; the MCP130 adds an internal 5 kΩ pull-up, while the MCP120 needs an external pull-up.
2 VDD power_in Supply voltage and monitored input, operating range 1.0 V to 5.5V (absolute maximum 7.0 V), with RESET asserted whenever VDD is below the trip-point voltage.
3 VSS power_in Ground reference for the device; inputs and outputs are rated -0.6 V to VDD + 1.0 V with respect to VSS.

CAD (KiCad official)

  • Symbol: MCP120T-450I
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mcp120t-450i-etched.step / mcp120t-450i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp120t-450i.step / mcp120t-450i.glb are the bare package body.
