TLE5046IC-PWM2-R050

Overview

XENSIV(TM) - TLE5046iC-AK-LR high end GMR wheel speed sensor with PWM protocol, ASIL B(D)

Infineon´s XENSIV™ 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.
