HAL245SO

Hallwee · Hall Switches · SOT-23-3L

HAL245SO from Hallwee, in a SOT-23-3L. 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 voltage pin. Operating range 3.8 V to 40 V; absolute maximum 60 V. Typical supply current 3.5 mA (max 7 mA). Bypass with 100 nF close to the pin.
2 GND power_in Ground reference pin. Common return for supply and open-drain output.
3 OUT output Open-drain (open-collector) Hall switch output. Pulls low when magnetic flux
