CPC5902 - Optically Isolated I2C Bus Repeater

Description

IXYS Integrated Circuits’ CPC5902 is a dual, optically isolated, bidirectional logic-bus repeater.

It galvanically isolates two open-drain logic signals, and provides a galvanic isolation of 3750Vrms.

Features

  • Bidirectionally Buffers Both I2C Signals.
  • Glitch-Free Operation.
  • Extends and Isolates I2C Interfaces.
  • Standard- and Fast-mode I2C Side B Fast-mode I2C Compliant VDDB > 4.5V.
  • Very Low EM and RF Generation - No Internal Clock.
  • SMBus Compatible VDDB = 3.3V.
  • Operates on 2.7V to 5.5V, Enabling Level Translation.
  • Slew-Limited Drivers Reduce EMI.
  • Powerdown to Hi-Z Doesn't Load I2C.
  • 3750Vrms Galvanic Isolation.
