SL1605TL from Slkor SLKORMICRO Elec, in a SOT-553-5. 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	NC	unconnected	No-connect pin. Leave floating or tie as convenient; not electrically bonded internally.
2	GND	power_in	Ground reference for the device. Connect to system ground; a 100nF decoupling capacitor should sit between VDD (pin 4) and this pin, close to the package.
3	NC	unconnected	No-connect pin. Leave floating or tie as convenient; not electrically bonded internally.
4	VDD	power_in	Supply input, 1.6V to 5.5V operating range (6V absolute max). Place a 100nF decoupling capacitor between VDD and GND as close to this pin as possible to filter supply noise.
5	OUTPUT	output	CMOS push-pull switch output. Drives low (VOL <= 0.1V @ 1mA) when applied magnetic field exceeds BOP (either polarity, omnipolar detection) and high (VOH >= VDD-0.1V @ 1mA) when field falls below BRP. Max sink/source current 5mA.
