GH1817LUA-A

GoChip Elec Tech Shanghai · Hall Switches · TO-92S

GH1817LUA-A from GoChip Elec Tech Shanghai, in a TO-92S. 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 voltage pin, operating range 3.5 to 30 V with an absolute maximum of -0.3 to +40 V, and the on-chip regulator tolerates supply variation within 3.5 to 30 V.
2 GND power_in Ground reference pin for the sensor.
3 VOUT output Open-drain output that sinks up to 50 mA and requires an external pull-up resistor (RL) to VDD; the output stage is rated for VOUT(OFF) up to 30 V with absolute maximum -0.3 to +40 V.
