The Hall Effect sensor IC TLE4941 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 optimised piezo compensation and the integrated dynamic offset
compensation enable easy manufacturing and elimination of magnet offsets.
The TLE4941C is additionally provided with an overmolded 1.8nF capacitor for
improved EMI performance.
