A1324LLHLX-T

Allegro MicroSystems LLC · Hall Sensor · SOT-23W

A1324LLHLX-T from Allegro MicroSystems LLC, in a SOT-23W. 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 Supply voltage input. Operating range 4.5 V to 5.5 V (nominal 5 V). Bypass to GND with a 0.1 uF ceramic capacitor placed close to the pin.
2 VOUT output Analog ratiometric output voltage. Quiescent output is nominally VCC/2 with zero applied field; output changes with magnetic flux density at a nominal sensitivity of 5 mV/G. Drives loads with output impedance suitable for high-impedance sensing.
3 GND power_in Ground reference for supply and output.

  • A1324LLHLX-T

CAD (KiCad official)

  • Symbol: A1324LLHLX-T
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23W (KiCad packages3D, STEP)
  • 3D model files: a1324llhlx-t-etched.step / a1324llhlx-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); a1324llhlx-t.step / a1324llhlx-t.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
a1324llhlx-t.step 59 KB You want the bare part, or you mark your own boards.
a1324llhlx-t-etched.step 1.4 MB You want the part with A1324LLHLX-T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 370 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:
