XENSIV(TM) - TLE5046iC-AK-LR high end GMR wheel speed sensor with direction detection, 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.
TLE5046iC-AK-LR with AK protocol
TLE5046iC-PWM2-R050 with PWM protocol
Summary of Features
Developed according to ISO 26262, compliant with the requirements of ASIL B(D)
Low jitter 0.02% due to high switching accuracy enables iTPMS
Two-wire current interface providing speed and direction information
Advanced stop-start capabilities enabled by - Innovative watchdog concept to guarantee maximum signal availability - No loss of direction information during start-stop condition
Wide operating junction temperature range -40°C to 190°C
Robustness against external magnetic disturbances up to 2mT through differential sensing principle
High sensitivity enables outstanding air gap performance along with immunity against y-displacement effects
Small sensor package 5x3mm without need of external capacitor saves module size, increases robustness against mechanical stress, and enables design freedom
Advanced EMC concept maximizes the availability of the sensor signal
New established Micro Break feature designed to be immune against disturbances on supply line
Potential Applications
Wheel Speed Sensing
Antilock braking system
iTPMS
Park assist systems and automated parking
Hill holder
