GH1230KSW
GoChip Elec Tech Shanghai · Hall Switches · SOT-23-3L
GH1230KSW from GoChip Elec Tech Shanghai, in a SOT-23-3L. 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 | Power supply pin; operating supply range is 2.8 V to 24 V (typical 12 V), with an absolute maximum of -0.3 V to +28 V. |
| 2 | VOUT | output | Open-drain output that requires an external pull-up resistor (818 Ω to 100 kΩ suggested in the application notes); maximum output low current is 50 mA and the output breakdown voltage is 32 V. |
| 3 | GND | power_in | Ground reference pin for the device. |
