Differential Two-Wire Hall Effect Sensor IC TLE4942 TLE4942C Features Two-wire PWM current interface Detection of rotation direction Airgap diagnosis Assembly position diagnosis Dynamic self-calibration principle Single chip solution No external components needed High sensitivity South and north pole pre-induction possible High resistance to piezo effects Large operating air-gaps Wide operating temperature range TLE4942C: 1.8nF overmolded capacitor PSSO2-1 Type TLE 4942 TLE 4942C Marking 4200E4 42C0E4 Ordering Code Q62705-K428 Q62705-K437 Package PSSO2-1 PSSO2-2 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 additional...
