HX3144ESO

HUAXIN · Hall Sensor · SOT-23

HX3144ESO 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, 2.5 V to 24 V (absolute max -28 to 28 V). Includes reverse-bias protection; typical supply current 2.5 mA at VDD = 5 V, B < Bop.
2 OUTPUT output Open-collector digital output. When magnetic field exceeds Bop (typ. 60 G, max 100 G) the output turns on (Vsat <= 400 mV at Iout = 20 mA). Sink capability up to 50 mA; leakage <= 10 uA at Vout = 20 V. Recommended pull-up R1 = 1 kOhm.
3 GND power_in Ground reference for the device.
