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.
