The Hall Effect sensor IC TLE4942 is designed to provide information about

rotational speed, direction of rotation, assembly position and limit airgap to modern

vehicle dynamics control systems and ABS. The output has been designed as a two

wire current interface based on a Pulse Width Modulation principle. 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 robustness and high EMC

resilience. State-of-the-art BiCMOS technology is used for monolithic integration of

the active sensor areas and the signal conditioning.

Finally, the optimised piezo compensation and the integrated dynamic offset

compensation enable easy manufacturing and elimination of magnet offsets.

The TLE4942C

is additionally provided with an overmolded 1.8nF capacitor for

improved EMI performance.
