TLE4941PLUSCB

TLE4941plusCB, a differential Hall sensor for measuring magnetically the car’s wheel speed, is the latest offspring of the extremely successful TLE4941 family, based on Infineon’s most recent sensor technologies for front-and backend. Designed as drop-in replacement the TLE4941plusCB is, as its predecessors, a single chip solution combining Hall sensor elements and both analogue and digital signal processing in one single chip. Its differential principle makes it immune to any kind of undesired magnetic fields and disturbances. The Hall element distance has been downsized to 2mm to be also fit for extremely small encoders. Several product improvements, both electrical and magnetic, have been put in place, such as an accelerated calibration during start-up phase and higher load dump robustness. The formerly optional firstedge detection, a feature for quick start-up, providing a reliable output signal even before calibration is fully completed, has now become standard. TLE4941plusC has a standard 2-wire current interface, high ESD robustness and works in the wide temperature range present in the harsh automotive environment. Magnetic and device offsets are cancelled by a sophisticated selfcalibration algorithm immediately after start-up. The TLE4941plusCB is an extremely robust product due to Infineon’s high quality standards as experienced automotive semiconductor supplier. After several hundred million units sold, Infineon’s active wheel speed sensors have largely proven to be the perfect match for wheel speed sensing in all aspects of functionality, robustness and flexibility.
