SL1603SH from Slkor SLKORMICRO Elec, 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, 1.6V to 5.5V operating range (6V absolute max). Requires a 100nF decoupling capacitor between VDD and GND placed close to the pin to filter supply noise.
2	OUTPUT	output	CMOS push-pull digital switch output. Drives low (VOL ~0.02V @ 1mA) when applied magnetic field exceeds
3	GND	power_in	Ground / 0V reference for supply and output.
