The chopped Hall Effect Switch comprises a Hall probe, a bias generator, compensation circuits, an oscillator and
an output transistor. The bias generator provides currents to the Hall probe and the active circuits. Compensation
circuits stabilize response of the IC over temperature and reduce the impact of process variations.
The Active Error Compensation rejects offsets in the signal path and reduces the impact of mechanical stress in
the package caused by molding, soldering and thermal effects.
The chopper technique together with the threshold generator and the comparator ensure high accurate magnetic
switching points.
