TLE4966L

概要

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.

特長

  • 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
