Functional Description

The TLE4966H 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 TLE4966H provides a speed signal at Q2 for every magnetic pole pair and a direction

information at Q1. The direction output switches 1

µs (min.) before the speed output.
