HX6474KSO

HUAXIN · Hall Switches · SOT-23

HX6474KSO from HUAXIN, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VDD	power_in	Supply input pin; the datasheet specifies an operating supply range of 2.5 V to 26.0 V, with reverse-bias protection on the power pin and an absolute maximum VDD of -28 V to 28 V.
2	Output	output	Open-collector output that sinks load current up to 25 mA, with an output voltage rating of 0.5 V to 28 V and a saturation voltage of 300 mV typical and 500 mV maximum at 20 mA.
3	GND	power_in	Ground terminal for the Hall switch.
