Description
The Hall Effect sensor IC TLE4941plusC is designed to provide information about rotational speed to modern
vehicle dynamics control systems and Anti-Lock Braking Systems (ABS). The output has been designed as a two
wire current interface. The sensor operates without external components and combines a fast power-up time
with a low cut-off frequency. Designed specifically to meet harsh automotive requirements, excellent accuracy
and sensitivity is specified over a wide temperature range and 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.
Finally, the optimized piezo compensation and the integrated dynamic offset compensation enables ease of
manufacturing and the elimination of magnetic offsets.
The TLE4941plusC is additionally provided with an overmolded 1.8 nF capacitor for improved EMC
performance.
*The device is compliant with all the requirements in ISO 26262:2018, 8-14 which are addressable by a
component supplier to support safety requirements up to ASIL B(D). Additional information is available in a
dedicated Application Note.
