TLE4941PLUSCAAMA1

TLE4941PLUSCAAMA1 is an advanced differential two-wire hall effect sensor IC. It is designed to provide information about rotational speed to modern vehicle dynamics control systems and Anti-Lock Braking Systems (ABS). The output has been designed as a two-wire current interface. The sensor operates without external components and combines a fast power-up time with a low cutoff frequency. Designed specifically to meet harsh automotive requirements, excellent accuracy and sensitivity are specified over a wide temperature range and robustness to ESD and EMC has been maximized. State-of-the-art BiCMOS technology is used for monolithic integration of the active sensor areas and the signal conditioning circuitry. Finally, the optimized piezo compensation and the integrated dynamic offset compensation enable ease of manufacturing and the elimination of magnetic offsets.
