TLE4941PLUSCXAMA1

TLE4941PLUSCXAMA1 is an advanced differential two-wire hall effect sensor IC. The 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 cutoff 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.

• Two-wire current interface, dynamic self-calibration principle
