HXU18UA from HUAXIN, 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 input for the Hall switch; the datasheet gives an operating supply range of 3.5 V to 20 V and an absolute maximum VDD of -20 V to 30 V. |
| 2 | GND | power_in | Ground terminal of the device; the datasheet states no pin-specific electrical limit for this pin. |
| 3 | Output | output | Open-collector output; the datasheet gives an absolute maximum VOUT of 0.3 V to 30 V, an output current of up to 25 mA, and a saturation voltage of at most 700 mV at 20 mA. |
