Product Description
Infineon's TLE5045iC is a high-end GMR wheel speed sensor designed for sophisticated vehicle control systems. It offers best-in-class jitter performance, making it ideal for precise wheel speed applications and as a component in indirect tire pressure monitoring systems (iTPMS). The sensor utilizes integrated giant magneto resistance (iGMR) technology, providing excellent sensitivity to magnetic fields over a wide temperature range. It is built to meet harsh automotive requirements with maximized robustness to electrostatic discharge (ESD) and electromagnetic compatibility (EMC) without external components. Its small package size and advanced EMC concept contribute to module size reduction, increased robustness, and design freedom.
