INFINEON  TLE4941C  霍尔效应传感器, Differential Speed and Direction Sensor, SSO, 2 引脚, 4.5 V, 20 V

The is a Hall Effect Sensor designed to provide information about rotational speed to modern vehicle dynamics control systems and 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. Excellent accuracy and sensitivity is specified for harsh automotive requirements as a wide temperature range, high ESD and EMC robustness. 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 enable easy manufacturing and elimination of magnet offsets.
