Features

Description

The CPC5903 is a dual, optically isolated, logic-bus

repeater. It isolates two open-drain logic signals while

• Bidirectionally Buffers I C SDA Signal

• Extends and Isolates I C Interfaces

providing 3750V

of galvanic isolation. When the

• Standard-mode and Fast-mode I C

two sides are powered by different supply voltages, it

also functions as a logic level translator for levels as

low as 2.7V or as high as 5.5V. Because the CPC5903

> 4.5V

DDB

• Operates on 2.7V to 5.5V

• Voltage Level Translation

• Slew-Limited Drivers Reduce EMI

• Powerdown to Hi-Z Does Not Load I C

• 3750V Galvanic Isolation

provides an isolated bidirectional buffer for the I C

data signal and a unidirectional buffer for the I C clock

signal, it is best suited for applications where clock

stretching is not required. This configuration also

• Single 8-pin Surface-Mount Package

requires the I C bus master to be on the Side A bus.

Applications

• Isolated Control and Signal Monitoring

• Power-over-Ethernet

Unlike transformer or capacitive isolators, optical

isolation passes DC signals and does not require

continuous clocking to ensure the proper state is

maintained. The CPC5903 always returns the buffered

signals to their proper state after transient

interruptions on either side.

• Power Supply High Side Interface

• I C Bus Length Extenders

• I C Logic Level Translation

Approvals

• UL 1577 Certified Component: File E76270

• EN/IEC 60950 Certified Component:

TUV Certificate: B 11 10 49410 007
