HX6382EST from HUAXIN, 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	VDD	power_in	Supply input. Operating range 1.65 V to 3.5 V (absolute max -0.3 V to 4.5 V). Recommend a 10 nF decoupling capacitor to GND.
2	OUTPUT	output	Push-pull digital Hall switch output. VOH >= VDD-0.2 V and VOL <= 0.2 V at IOUT = 0.5 mA. Max output current 1 mA; goes low (on-state) when applied field exceeds BOP (~~±20 G typ) and releases at BRP (~~±15 G typ).
3	GND	power_in	Ground reference (0 V) for the device.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`hx6382est.step`	59 KB	You want the bare part, or you mark your own boards.
`hx6382est-etched.step`	1.9 MB	You want the part with `HX6382EST` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 443 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.
