(Magnetic Field Detection Mechanism)

Flux Direction

Figure 13. Direction of the detectable magnetic field

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.

Magnetic Flux Density [mT]

Figure 14. S-pole and N-pole Detection

The omnipolar 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.

The point where magnetic flux density restores a 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.
