CC6103ST from Cross chip, 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, 2.5 V to 5.5 V operating range (absolute max -0.3 V to 5.5 V). Typical quiescent current 2 mA at 5.0 V. A bypass capacitor to GND is recommended.
2	VOUT	output	Latching digital output from the Hall comparator with current-limited push-pull power stage. Sinks/sources up to 50 mA into a resistive load with VSAT <= 0.4 V at 50 mA. Rise time ~1.0 us and fall time ~2.5 us with RL=820 ohm, CL=10 pF.
3	GND	power_in	Ground reference for the supply and output stage.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cc6103st.step`	59 KB	You want the bare part, or you mark your own boards.
`cc6103st-etched.step`	1.7 MB	You want the part with `CC6103ST` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 408 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.
