The Infineon Hall effect sensor IC TLE4941plusC 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 cut-off frequency. Designed specifically to meet harsh automotive requirements, excellent accuracy and sensitivity is 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 enables ease of manufacturing and the elimination of magnetic offsets. The TLE4941plusC is additionally provided with an overmolded 1.8nF capacitor for improved EMC performance.
