Type
TLE4953C
TLE4953
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.
