Overview
The Hall Effect sensor IC TLE4941C is designed to provide information about rotational speed to modern vehicle dynamics control systems and ABS. The output has been designed as a two wire current interface. The sensor operates without external components and combines a fast powerup time with a low cut-off frequency. Excellent accuracy and sensitivity is specified for harsh automotive requirements as a wide temperature range, high ESD and EMC robustness. State-of-the art BiCMOS technology is used for monolithic integration of the active sensor areas and the signal conditioning circuitry.
