Infineon´s XENSIV TLE5045iC and TLE5046iC wheel speed sensor family is designed for sophisticated vehicle control systems. The family consists of the designed-to-cost, speed-only TLE5045iC, and the high-end TLE5046iC providing not only direction detection but also offering true ‘zero-speed’ capability as well as possibilities for self-diagnostics.
These sensors show best-in-class jitter performance, thus being ideal for wheel speed applications. The rotational speed is sensed with high accuracy, enabling the sensor to be used for indirect tyre pressure monitoring systems (iTPMS). It is based on integrated giant magneto resistance (iGMR). Excellent sensitivity to magnetic fields is specified over a wide temperature range.
To meet harsh automotive requirements, robustness to electrostatic discharge (ESD) and electromagnetic compatibility (EMC) are maximised without the need for additional external components.
