Figure 16. N-pole Detection

The OUT2 pin detects and outputs for the N-pole only. Since the OUT2 pin output is unipolar, the output does not respond

to the S-pole. The dual output 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.
