The differential Hall Effect sensor TLE4953 is designed to provide information about

rotational speed and direction of rotation to modern transmission and ABS systems. 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 wide frequency range. 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 optimized piezo compensation and the integrated dynamic offset

compensation enable easy manufacturing and elimination of magnetic offsets. Adaptive

hysteresis concept increases the noise immunity. The TLE4953C is additionally

provided with an overmolded 1.8 nF capacitor for improved EMI performance.
