Dynamic Differential Hall Effect Sensor IC
TLE4923
Bipolar IC
1
Overview
1.1
Features
• Advanced performance
• Higher sensitivity
• Symmetrical thresholds
• High piezo resistivity
• Reduced power consumption
• South and north pole pre-induction possible
• AC coupled
• Digital output signal
• Two-wire interface
• Large temperature range
• Large airgap
• Low cut-off frequency
• 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. The integrated circuit (based on Hall effect) provides a digital signal
output with frequency proportional to the speed of rotation. Unlike other rotational
sensors differential Hall ICs are not influenced by radial vibration within the effective
airgap of the sensor and require no external signal processing.
