Precise magnetic switching points and high temperature stability are achieved by active compensation circuits and chopper techniques on chip. The TLE4966H provides a speed signal at Q2 for every magnetic pole pair and a direction information at Q1. The direction output switches 1µs (min.) before the speed output. TLE4966H Circuit Description The chopped Double Hall Switch comprises two Hall probes, bias generator, compensation circuits, oscillator, and output transistors. The bias generator provides currents for the Hall probes 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 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 points.
