mt8631at.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 3 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

MT8631AT

Magn Tek · Hall Sensor · SOT-23-3L

MT8631AT from Magn Tek, in a SOT-23-3L. 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 Vcc power_in Positive supply voltage input. Operating range 2.0V to 5.5V (absolute max 7V). Typical supply current ~1.2uA at Vcc=3.6V, ~600nA at Vcc=2.0V.
2 Out output Push-pull digital output. Drives LOW (VOL <= 0.4V at Iout=5mA) when
3 GND power_in Ground reference for the device.

CAD (KiCad official)

  • Symbol: MT8631AT
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: mt8631at-etched.step / mt8631at-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mt8631at.step / mt8631at.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mt8631at.step 59 KB You want the bare part, or you mark your own boards.
mt8631at-etched.step 1.4 MB You want the part with MT8631AT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 358 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: Magn Tek datasheet (11 pp, sha256 0d745458b0d3ea52, retrieved 2026-08-17, tier: lcsc)
  • 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).
