Product Description
Product Overview
Infineon's TLE5046iC is a high-end GMR wheel speed sensor with integrated direction detection, designed for sophisticated automotive control systems. It offers best-in-class jitter performance, making it ideal for precise wheel speed applications, including indirect tire pressure monitoring systems (iTPMS). The sensor utilizes integrated giant magneto resistance (iGMR) technology, providing excellent sensitivity over a wide temperature range. It is built to meet stringent automotive requirements for robustness against electrostatic discharge (ESD) and electromagnetic compatibility (EMC) without external components.
