XLSEMI · Hall Switches · SOT-23-3

XL522 from XLSEMI, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Power supply input pin. Supports DC 3.3V-45V wide-voltage operation with reverse-supply protection (VDDR = -45V). Recommended 0.1uF decoupling capacitor (C1) to GND.
2 OUT output Open-collector Hall switch output. Requires an external pull-up resistor to Vpull (up to 50V). Sinks up to 40mA with typical Vsat = 0.2V at 30mA. OUT = L when B > BOP (+60Gs typ), OUT = H when B < BRP (-60Gs typ), with latching hysteresis.
3 GND power_in Ground reference pin for the device.
