TLE4966G

概要

XENSIV™ - TLE4966G double Hall-effect sensor designed specifically for highly accurate automotive applications

The TLE4966G is an integrated circuit double Hall-effect sensor designed specifically for highly accurate applications in the automotive sector. Precise magnetic switching points and high temperature stability are achieved by active compensation circuits and chopper techniques on chip. They provide 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
  • SMD package PG-TSOP6-6-9
