General 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.

When the two sides’ supply voltages are configured with different voltages, the CPC5902 also functions as a logic level translator for levels as low as 2.7V or as high as 5.5V.

Key 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.
