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. |
