TLE4941PLUSC
XENSIV™ - TLE4941plusC magnetic speed sensor for modern vehicle dynamics control systems and Anti-Lock Breaking Systems
Our Infineon magnetic Hall effect sensor TLE4941plusC provides information about rotational speed to modern vehicle dynamics control systems and Anti-Lock Braking Systems (ABS). The output is designed as a two wire current interface. The device operates without external components and combines a fast power-up time with a low cut-off frequency. Thus the product is dedicated to meet harsh automotive requirements, excellent accuracy and sensitivity is specified over a wide temperature range, moreover robustness to ESD and EMC has been maximized. State-of-the art BiCMOS technology is used for monolithic integration of the active sensor areas and the signal conditioning circuitry. Last, but not least the optimized piezo compensation and the integrated dynamic offset compensation enables ease of manufacturing and the elimination of magnetic offsets. Infineon´s TLE4941plusC is additionally provided with an overmolded 1.8 nF capacitor for improved EMC performance.
The product is compliant to ISO 26262:2018 according to part 8, clause 14 up to ASIL B(D), in the context of existing Assumptions of Use from
ISO 26262:2018 part 2, clause 6.4.4. Additional information is available in a dedicated application note,link to.
