TLE5045ICR050HALA1

TLE5045ICR050HALA1 is an ASIL B(D, high-end GMR wheel speed sensor optimized for use with load resistor Rm ≤50 ohm. It is a wheel speed sensor without direction detection designed for sophisticated vehicle control systems. As the successor of the TLE5041plusC, the sensor shows best-in-class jitter performance, thus being the best choice for wheel speed applications. The rotational speed is sensed with high accuracy, enabling the sensor to be used as a component of indirect tire pressure monitoring systems (iTPMS). It is based on integrated giant magneto resistance (iGMR). Excellent sensitivity to magnetic field is specified over a wide temperature range. To meet harsh automotive requirements, robustness to electrostatic discharge (ESD) and electromagnetic compatibility (EMC) was maximized without the need for additional external components.
