Product Overview

The TLE4906-2K is a high-precision, unipolar Hall-effect switch designed for demanding automotive applications requiring accurate position sensing. It features highly accurate switching thresholds that remain stable across operating temperatures up to 150C. The device operates from an unregulated power supply, offers high sensitivity and stability of magnetic switching points, and is robust against mechanical stress due to its Active Error Compensation technology. With a digital output, superior temperature stability, low jitter, and high ESD performance, the TLE4906-2K is ideal for position sensing in automotive environments.
