TLE 4941plusC, a differential Hall sensor for measuring magnetically the car´s
wheel speed, is the latest offspring of the extremely successful TLE 4941 family,
based on Infineon’s most recent sensor technologies for front- and backend.
Designed as drop-in replacement the TLE 4941plusC 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 2 mm 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 first-edge-detection,
a feature for quick start-up, providing a reliable output signal even before calibration
is fully completed, has now become standard.
TLE 4941plusC 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 TLE 4941plusC 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.
