HAL1201NSO

Hallwee · Hall Switches · SOT-23-3L

HAL1201NSO from Hallwee, in a SOT-23-3L. 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 VCC power_in Supply voltage pin, operating range 1.8 V to 5.5 V in the DC table (absolute maximum 6 V), with an external bypass capacitor recommended close to the device.
2 OUT output CMOS output that goes low when a south pole field exceeds Bop (50 G max) and releases below Brp, rated for 0.5 mA with VOL of 0.2 V max (absolute maximum 6 V and 1 mA).
3 GND power_in Ground reference pin for the supply and output.
