Functional Description
The TLE4906H is an integrated circuit Hall-effect sensor designed specifically for highly accurate applications. Precise magnetic switching points and high temperature stability are achieved by active compensation circuits and chopper techniques on chip.
TLE4906H
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 thresh...
