XENSIV™ - TLE4966L double Hall-effect sensor designed specifically for highly accurate 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.
Summary of 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 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
Potential Applications
Index counting
Rotational speed and direction detection
Motor driven positioning systems window lifter,power closing systems,sun blinds,garage door
Applications
Cordless vacuum cleaners
Reversible seatbelt pretensioner
