(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 operating point (Bop), the output goes HIGH. As the magnet gets closer to the
IC and the magnetic density rises to the operating 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, when the output returns HIGH. (This point,
where the 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.
Therefore, ensures that the Hall IC is configured perpendicular to the top layer.
