MCP9700AT-E/TT

Microchip · Temperature and Humidity Sensor · SOT-23

MCP9700AT-E 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 Power supply input. Operating range 2.3V to 5.5V. Bypass with a 0.1 µF ceramic capacitor to GND placed close to the pin.
2 VOUT output Analog temperature output voltage. Transfer function VOUT = (10.0 mV/°C) x TA + 500 mV; e.g. 500 mV at 0°C, 750 mV at 25°C. Drives loads down to typical output impedance ~20 Ω; recommend >=100 kΩ load and up to 1000 pF capacitive load.
3 GND power_in Ground reference for the device.

  • MCP9700AT-EE/TO

CAD (KiCad official)

  • Symbol: MCP9700AT-E
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mcp9700at-e-etched.step / mcp9700at-e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp9700at-e.step / mcp9700at-e.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mcp9700at-e.step 59 KB You want the bare part, or you mark your own boards.
mcp9700at-e-etched.step 1.7 MB You want the part with MCP9700AT-E already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 423 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 (22 pp, sha256 8fa5dbaa5899ea84, 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).
