HAL204SO

Hallwee · Linear Hall Sensors · SOT-23-3L

HAL204SO 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 VCC power_in Supply voltage input. Operating range 1.65 V to 5.5 V (typ 3.3 V); absolute maximum 6 V. Bypass with 0.1 µF to 1 µF ceramic close to the pin.
2 OUT output CMOS Hall-switch output. Drives low when the sensed magnetic flux density exceeds the operate point Bop and releases high once flux drops below the release point Brp. VOH ≥ VDD-0.2 V @ IOUT=-0.5 mA; VOL ≤ 0.2 V @ IOUT=+0.5 mA. Absolute max output current 1 mA, absolute max output voltage 6 V. No external pull-up required.
3 GND power_in Ground reference / negative supply return.
