hx6639iua-a.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 -> 0 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

HX6639IUA-A

HUAXIN · Hall Sensor · TO-92S

HX6639IUA-A from HUAXIN, in a TO-92S. 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 2.8 V to 6.0 V (absolute max 8 V); typical supply current 3.3 mA at 5 V. Bypass with a 1 nF/10 V decoupling capacitor to GND per the application diagram.
2 GND power_in Ground reference. Must be tied solidly to the supply ground return.
3 OUTPUT output Push-pull analog output; no pull-up required. Quiescent output equals VDD/2 at 0 Gs (VNULL ≈ 2.5 V at 5 V). A south-pole field raises Vout above VDD/2 (up to ~4.9 V at max range), a north-pole field lowers it (down to ~0.01 V); sensitivity 4.0 mV/Gs over ±600 Gs. Drive capability 1.5 mA typical; absolute-max output current 20 mA. A 10 nF/10 V output filter capacitor to GND is recommended.

  • 3D model files: hx6639iua-a-etched.step / hx6639iua-a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hx6639iua-a.step / hx6639iua-a.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
hx6639iua-a.step 27 KB You want the bare part, or you mark your own boards.
hx6639iua-a-etched.step 1.7 MB You want the part with HX6639IUA-A already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 433 faces against 19 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.
