Product Overview

The Infineon TLE4953x series are differential Hall Effect transmission speed sensors designed for modern transmission and ABS systems. These sensors provide crucial information on rotational speed and direction, utilizing a two-wire current interface based on Pulse Width Modulation (PWM). They operate without external components, offering fast power-up times and a wide frequency range. Engineered for harsh automotive environments, they boast excellent accuracy, sensitivity, a wide operating temperature range, high ESD robustness, and strong EMC resilience. The TLE4953C variant includes an integrated 1.8 nF capacitor for enhanced EMI performance. These sensors are AEC-Q100 qualified.
