Infineon TLE49421CHAMA2

The Infineon XENSIVTM Hall effect sensor IC TLE4942-1C is designed to provide information about rotational speed, direction of rotation, assembly position and limit airgap to modern vehicle dynamics control systems and ABS. The output has been designed as a two wire current interface based on a Pulse Width Modulation (PWM) principle. 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 robustness and high EMC resilience. State-of-the-art BiCMOS technology is used for monolithic integration of the active sensor areas and the signal conditioning.Finally, the optimized piezo compensation and the integrated dynamic offset compensation enable easy manufacturing and elimination of magnet offsets. The TLE4942-1C is additionally provided with an overmolded 1.8 nF capacitor for improved EMI performance.
