XENSIV™ - TLE4941C magnetic speed sensor with dynamic self-calibration principle

Infineon XENSIV 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 power-up 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. Finally, the optimized piezo compensation and the integrated dynamic offset compensation enable easy manufacturing and elimination of magnet offsets. The speed sensor is additionally provided with an overmolded 1.8 nF capacitor for improved EMI performance.
