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.
- 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 195°C without damage
- Low jitter (typ. 1 μs)
- 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
- Index counting
- Rotational speed and direction detection
- Motor driven positioning systems window lifter,power closing systems,sun blinds,garage door
