MCP130T-300I

Microchip · Supervisor and Reset ICs · SOT-23

MCP130T-300I from Microchip, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive supply, 1.0 V to 5.5 V (7.0 V abs max). Monitored input; the internal bandgap comparator asserts RESET when VDD drops below the 3.0 V trip point. Bypass with 0.1 µF close to the pin for transient immunity. Typical IDD ≈ 45 µA (60 µA max).
2 RST output Active-low reset output (open-drain NMOS). On the MCP130 an internal 5 kΩ pull-up to VDD is included. Asserted (VOL ≤ 0.4 V at IOL = 3.2 mA, VDD = VTRIP_MIN) whenever VDD < VTRIP, and remains asserted for tRPU ≈ 350 ms (150-700 ms) after VDD returns above VTRIP. VOH ≥ VDD − 0.7 V at IOH = 50 µA when de-asserted (MCP130 only).
3 VSS power_in Ground / negative supply return. All voltages are referenced to VSS. Absolute-max on any pin is −0.6 V to VDD + 1.0 V referenced to VSS.

CAD (KiCad official)

  • Symbol: MCP130T-300I
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mcp130t-300i-etched.step / mcp130t-300i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp130t-300i.step / mcp130t-300i.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mcp130t-300i.step 59 KB You want the bare part, or you mark your own boards.
mcp130t-300i-etched.step 2.2 MB You want the part with MCP130T-300I already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 524 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Microchip datasheet (16 pp, sha256 08f3a0576f4b76c0, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
