XLSEMI · Hall Switches · SOT-23-3

XL544 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 Supply input pin, DC 3.3V to 45V wide operating range (absolute max -50V to +50V). Supports input reverse-polarity protection. Bypass with 0.1uF ceramic to GND close to the pin.
2 OUT output Open-collector digital output; requires an external pull-up resistor (RL) to Vpull. Sinks up to 50mA (Vsat ~0.2V at 30mA). Output goes LOW when B > BOP (south pole facing the marked face) and HIGH when B < BRP.
3 GND power_in Device ground reference pin.
