Functional Description
The TLE4966L is an integrated circuit double 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.
The TLE4966L 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.
