# MCP101T-460I

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

MCP101T-460I 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 | VDD | power_in | Supply voltage input monitored against the trip point (4.35 V min, 4.475 V typ, 4.60 V max for -460), operating range 1.0 V to 5.5 V, absolute maximum 7.0 V. |
| 2 | RST | output | Active-high push-pull reset output (MCP101) asserted whenever VDD is below the trip point and held for 350 ms typical after VDD rises above it, valid down to VDD = 1.0 V. |
| 3 | VSS | power_in | Ground reference for the device. |

## CAD (KiCad official)

- Symbol: `MCP101T-460I`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3 (KiCad packages3D, STEP)
- 3D model files: `mcp101t-460i-etched.step` / `mcp101t-460i-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mcp101t-460i.step` / `mcp101t-460i.glb` are the bare package body.
