Tle 4941/42-x(c): Wheel Speed Sensing family
THe Tle4941 iS THe HigH runner of infineon’s differential Hall sensor ic family for active
signal processing in one chip. The Tle4941 has a standard two-wire current interface and high
environment. magnetic and device off sets are cancelled by a sophisticated self-calibration algorithm
capacitor (-c types) and first edge detection (-1 types). The Tle4941 is an extremely robust product,
due to infineon’s high quality standards as an experienced automotive semiconductor supplier. After
several hundred million units sold, the Tle4941 has proven to be the perfect match for wheel speed
sensing in all aspects of functionality, robustness and flexibility.
