Precise magnetic switching points and high temperature stability are achieved by active compensation circuits and chopper techniques on chip. The sensor provides a speed output at Q2 with the status (high or low) corresponding to the magnetic field value. For positive magnetic fields (south pole) exceeding the threshold BOP the output is low, whereas for negative magnetic fields (north pole) lower than BRP the output switches to high. The output Q1 can be either high or low depending on the direction of rotation of the pole wheel. This direction information is calculated internally.

The bias generator provides currents for the Hall probes and the active circuits. Compensation circuits stabilize the temperature behavior and reduce influence of technology variations. The Active Error Compensation rejects offsets in signal stages and the influence of mechanical stress to the Hall probes caused by molding and soldering processes and other thermal stresses in the package. This chopper technique together with the threshold generator and the comparator ensures high accurate magnetic switching thresholds.
