HX6659ISO-B

HUAXIN · Hall Sensor · SOT-23

HX6659ISO-B from HUAXIN, 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 Supply voltage input. Operating range 2.8V to 6.0V (absolute max 8V, reverse -0.5V). Typical supply current 3.3mA at 5.0V. Bypass with 1nF/10V ceramic to GND close to the pin.
2 OUTPUT output Analog ratiometric output proportional to magnetic flux density perpendicular to the top of the package. Quiescent (B=0) output VNULL ≈ VDD/2 (2.5V typ at VDD=5V); rises above VNULL for a south pole and falls below for a north pole. Max drive current 1.5mA (absolute max IOUT=20mA); recommend a 10nF/10V filter cap to GND.
3 GND power_in Device ground reference. Return path for supply and output filter capacitors.

Two STEP files. Same geometry, different body top:

File Size Use it when
hx6659iso-b.step 59 KB You want the bare part, or you mark your own boards.
hx6659iso-b-etched.step 2.1 MB You want the part with HX6659ISO-B already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 493 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: HUAXIN datasheet (13 pp, sha256 ff93559b4d077b22, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
