... Protection against reversed polarity The differential Hall effect sensor TLE4923 is compatible to the TLE4921-3U, except for having a 2-wire interface. The TLE4923 provides high sensitivity, a superior stability over temperature and symmetrical thresholds in order to achieve a stable duty cycle. TLE4923 is particularly suitable for rotational speed detection and timing applications of ferromagnetic toothed wheels such as in anti-lock braking systems, transmissions, crankshafts, etc ...
