TLE5046iC Technical product description High End GMR Wheel Speed Sensor with direction detection, ASIL B(D) About this document Scope and purpose High-level description of the product features and technical characteristics as primary information about the functionality of the TLE5046iC High End GMR Wheel Speed Sensor with direction detection, ASIL B(D) Intended audience Automotive suppliers interested in wheel speed sensor applications About this product Description Infineon s TLE5046iC is a wheel speed sensor with direction detection designed for sophisticated vehicle control systems. TLE5046iC 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 of additional external components.
