TLE5045IC-R050

The Infineon Technologies TLE5045iC is a high-end GMR wheel speed sensor without direction detection, designed for sophisticated vehicle control systems. It excels in wheel speed applications with best-in-class jitter performance, enabling high accuracy rotational speed sensing. This makes it suitable for use in indirect tire pressure monitoring systems (iTPMS).

Key features include a wide operating junction temperature range from -40°C to 190°C, ensuring robust performance in harsh automotive environments. It utilizes a two-wire current interface (7mA/14mA) for speed information and boasts robustness against external magnetic disturbances up to 2mT due to its differential sensing principle. The sensor's high sensitivity provides outstanding air gap performance and immunity against y-displacement effects.

The TLE5045iC comes in a small 5x3mm sensor package, which eliminates the need for an external capacitor, saving module size and increasing robustness against mechanical stress. Its advanced EMC concept maximizes the availability of the sensor signal, and a new Micro Break feature is designed to be immune against disturbances on the supply line. Developed according to ISO 26262, it is compliant with the requirements of ASIL B(D).
