MCP111T-475E

Microchip Tech · Monitors & Reset Circuits · SOT-23

MCP111T-475E 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 VOUT output Output state is high when VDD is above VTRIP while falling (VDD rising: above VTRIP + VHYS) and low when VDD is below VTRIP; MCP111 has an open-drain output that requires an external pull-up resistor.
2 VSS power_in Ground reference for the device.
3 VDD power_in Positive power supply; the operating voltage range is 1.0 V to 5.5 V.

CAD (KiCad official)

  • Symbol: MCP111T-475E
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mcp111t-475e-etched.step / mcp111t-475e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp111t-475e.step / mcp111t-475e.glb are the bare package body.
