Functional Block Description

The chopped Hall IC Switch comprises a Hall probe, bias generator, compensation circuits, oscillator and output

transistor.

The bias generator provides currents for the Hall probe and the active circuits. Compensation circuits stabilize the

temperature behavior and reduce technology variations.

The Active Error Compensation rejects offsets in signal stages and the influence of mechanical stress to the Hall

probe caused by molding and soldering processes and other thermal stresses in the package.

This chopper technique together with the threshold generator and the comparator ensure high accurate magnetic

switching points.
