TLE4966L High Precision Hall-Effect Switch with Direction Detection About this document Features 2.7 V to 24 V supply voltage operation Operation from unregulated power supply High sensitivity and high stability of the magnetic switching points High resistance to mechanical stress by active error compensation Reverse battery protection (-18 V) Superior temperature stability Peak temperatures up to 195C without damage Low jitter (typically 1 s) Digital output signals Bipolar version Excellent matching between the 2 Hall probes Hall plate distance 1.45 mm Direction & speed information Direction signal switches before the speed signal Target applications The TLE4966L is an integrated circuit double Hall-effect sensor designed specifically for highly accurate applications. Precise magnetic switching points and high temperature stability are achieved by active compensation circuits and chopper techniques on chip. The IC provides a speed signal at Q2 for every magnetic pole pair and a direction information at Q1, which is provided before the speed signal.
