(Magnetic Field Detection Mechanism)

The Hall IC cannot detect magnetic fields that run horizontal to the package top layer.

Be certain to configure the Hall IC so that the magnetic field is perpendicular to the top layer.

The OUT1 pin detects and outputs for the S-pole only. Since the OUT1 pin output is unipolar, the output does not respond

to the N-pole.
