Key Features

  • Two independent channels for interfacing with variable-reluctance sensors.
  • Internal hysteresis set at 160 mV for stable operation.
  • Built-in diagnostic mode to test for sensor degradation or loss of physical connector.
  • Designed to work from a 5.0 V ± 10% supply voltage.
  • Pb-free packages available.
  • Active clamp on each input to limit voltage and prevent substrate current injection.
  • Input protection up to ±250 V with R1 = R2 = 22 kΩ.

Applications

  • Anti-Skid Braking and Traction Control systems.
  • Vehicle Stability Control systems.
  • Drive Belt Slippage Detection.
  • Crankshaft/Camshaft Position Sensing.
