(Magnetic Field Detection Mechanism)
The bipolar detection Hall IC detects magnetic fields running perpendicular to the top surface of the package. There is an inverse
relationship between magnetic flux density and the distance separating the magnet and the Hall IC: when distance increases
magnetic density falls. When it drops below the operate point (Bop), output goes HIGH. When the magnet gets closer to the IC
and magnetic density rises, to the operate point, the output switches LOW. In LOW output mode, the distance from the magnet to
the IC increases again until the magnetic density falls to a point just below Bop, and output returns HIGH. (This point, where
magnetic flux density restores HIGH output, is known as the release point, Brp.) This detection and adjustment mechanism is
designed to prevent noise, oscillation and other erratic system operation.

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.
