Product Overview

The TLE4966L is a high-precision, integrated double Hall-effect sensor IC designed for demanding applications requiring accurate direction and speed detection. It features a wide supply voltage range (2.7 V to 24 V), operation from unregulated power supplies, and exceptional stability of magnetic switching points due to active error compensation and chopper techniques. The device provides distinct speed and direction signals, with the direction signal outputting prior to the speed signal, enabling precise rotational analysis. Its robust design includes reverse battery protection and resistance to mechanical stress, making it suitable for applications where reliability and accuracy are paramount.
