GH39FKSW

GoChip Elec Tech Shanghai · Hall Sensor · SOT-23-3L

GH39FKSW from GoChip Elec Tech Shanghai, 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 Positive supply voltage. Operating range 3.0 V to 6.5 V; absolute maximum 15 V. Typical supply current 6.0 mA (max 9.0 mA).
2 VOUT output Analog output. Emitter-follower output proportional to magnetic flux density. Quiescent output 2.25-2.75 V at B=0 (Vcc=5 V), sensitivity 1.45-2.0 mV/GS, output span roughly VH=0.80-1.05 V to VL=3.95-4.20 V over ±1000 GS. Recommended load impedance >10 kΩ; absolute max output current 10 mA.
3 GND power_in Ground reference for supply and output signal.
