HX258EST 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 1.7 V to 5.5 V (absolute max 6 V). Bypass with 10 nF to GND close to the pin.
2	OUTPUT	output	Open-drain Hall switch output. Requires external pull-up (10 kΩ typical) to VDD. VOL ≤ 0.2 V at 0.5 mA sink; leakage IOFF ≤ 1 μA in the off state; max output current 1 mA.
3	GND	power_in	Device ground reference.
