Product Overview
The Infineon TLE4941plusC is an advanced differential two-wire Hall Effect sensor IC designed for high-performance rotational speed sensing in automotive applications, particularly for vehicle dynamics control systems and Anti-Lock Braking Systems (ABS). It features a two-wire current interface, dynamic self-calibration for accurate performance over a wide temperature range, and robustness against ESD and EMC. The sensor operates without external components, offering a fast power-up time and low cut-off frequency. Its monolithic integration using BiCMOS technology, optimized piezo compensation, and integrated dynamic offset compensation ensure manufacturing ease and magnetic offset elimination. The TLE4941plusC includes an overmolded 1.8 nF capacitor for enhanced EMC performance and is suitable for applications with small pitches (2mm Hall element distance).
