TLE4906L
Circuit 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.
