**XLSEMI** · Linear Hall Sensors · SOT-23-3

XL594 from XLSEMI, in a SOT-23-3. 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 input pin supporting a wide DC 3V~8V operating range (absolute maximum -0.3 to 50V). |
| 2 | OUT | output | Analog output pin whose voltage is proportional to supply voltage and magnetic field strength (quiescent 2.5V at 5V supply, absolute maximum -0.3 to 40V, max 1mA output current). |
| 3 | GND | power_in | Chip ground pin. |
