TLE4942 Datasheet, PDF (2/18 Pages) Infineon Technologies AG – Differential Two-Wire Hall Effect Sensor IC

TLE4942, TLE4942C
The Hall Effect sensor IC TLE4942 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 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 optimised piezo compensation and the integrated dynamic offset
compensation enable easy manufacturing and elimination of magnet offsets.
The TLE4942C is additionally provided with an overmolded 1.8nF capacitor for
improved EMI performance.
