Product description

iC-JX is a bidirectional I/O device with 4x4 high-side driver stages. The input or output function can be separately selected for nibbles of four I/O stages.

Each nibble can be individually programmed with various filtering options for the debouncing of I/O pin signals or overcurrent messages, with current sources for defining of levels at the I/Os and also with a flash pulse function.

To enable communication with the controller the device includes a parallel and a SPI compatible serial interface.


  • 16 bidirectional input/output stages at 24 V
  • Input/output mode programmable in 4-channel blocks
  • Short-circuit-proof high-side drivers with diagnosis function
  • 500 mA pulse and 150 mA permanent load driving capability
  • Active flyback circuit
  • Load diagnosis for driver current, output voltage and impedance (cable break, resistance and short circuits)
  • 10-bit A/D converter for the generation of diagnosis measurement values
  • Safety devices (voltage monitor, temperature sensor with warning and shutdown features, power output enable pin)
  • Programmable interrupt generation with event storage facility
  • Variable digital filters for the debouncing of I/O signals
  • Fast 8-bit parallel or serial SPI-compatible µC interface permits SPI bus and daisy chain configuration
  • Logic supply from 3 V upwards


  • Industrial 24 V applications
  • Lamp switches with diagnostic features
  • Inductive load driver circuits for relays and valves etc.
