GH1881

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

GH1881 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; normal operating range is 2.8 to 24 V, with an absolute maximum rating of -0.3 to +28 V.
2 GND power_in Ground reference pin for the sensor IC.
3 VOUT output Open-drain output that requires an external pull-up resistor (820 Ω to 100 kΩ, depending on the load current needed); the output sinks up to 50 mA low-level current (IOUTL) with a 32 V off-state breakdown rating.
