Product description

iC-NX is an eight-fold LED pulse driver for light curtain systems.

The device features an adjustable LED current sink of 0.4 to 1.8 A (at room temperature). The positive temperature coefficient of the LED current sink largely compensates for the decrease in LED efficiency with a rise in temperature.

Features

  • 1 to 8 channels LED pulse current can be adjusted from 0.4 to 1.8 A via a single external low power resistor
  • Positive pulse current temperature coefficient permits compensation of decreases in LED efficiency
  • Short light pulses from 0.5 µs with steep edges
  • Low standby current; device activated by input data
  • Diagnostic message generated with LED interrupts
  • LED short-circuit recognition
  • Control logic with three-stage shift register
  • Output buffer with 120 Ω line adaptation
  • Supply voltage range of 4.75 to 6 V
  • Thermal and low-voltage shutdown

Applications

  • Protective equipment (ESPE)
  • Light curtain LED driver
