HX6383EST 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 input. Operating range 1.65 V to 6.0 V (absolute max 7 V). Bypass with a 10 nF capacitor to GND per recommended application circuit.
2	Output	output	Push-pull digital Hall switch output. Drives VOH >= VDD-0.2 V (source) or VOL <= 0.2 V (sink) at 0.5 mA; max output current 1 mA. Off-state leakage <= 1 uA. No external pull-up required.
3	GND	power_in	Ground reference for supply and output.
