CPC5902GS

Overview

The CPC5902GS is a dual, optically isolated, bidirectional logic-bus repeater manufactured by IXYS Integrated Circuits. It galvanically isolates two open-drain logic signals, specifically designed for I2C bus applications. The device operates within a supply voltage range of 2.7V to 5.5V and supports a wide operating temperature range from -40°C to +85°C. Key electrical specifications include an isolation voltage of 3750 Vrms and a power dissipation rating of 800 mW. It is housed in an 8-SMD,鸥翼 (gull-wing) package with a moisture sensitivity level of 3.

Feature Summary

• Provides galvanic isolation between two open-drain logic signals
• Functions as a bidirectional repeater for I2C buses
• Supports standard logic output configurations

Applications

• I2C bus signal extension
• Galvanic isolation of digital communication lines
• Bidirectional data transfer across isolation barriers

Procurement Notes

Verify component authenticity through authorized channels due to the discontinued status of this part number. Confirm that the specific suffix matches the required package type and lead-free compliance standards. Check for available alternative sources or equivalent replacement components if immediate procurement is necessary. Ensure storage conditions adhere to the specified moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this component when designing systems requiring robust galvanic isolation for I2C communication lines. Consider the 3750 Vrms isolation rating for safety-critical applications. Evaluate the 2.7V to 5.5V supply range compatibility with the target logic levels. Assess the thermal performance given the 800 mW power dissipation limit and the operational temperature range constraints.

Part Context

This component belongs to the CPC5903 series family, which includes similar optically isolated bus repeaters. It shares functional similarities with the CPC5902 but may differ in specific pinout or packaging details. The series is designed for high-reliability digital isolation tasks. Understanding the broader family context helps in identifying compatible alternatives or related components within the manufacturer's portfolio.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided documentation. Verify availability of direct replacements such as the CPC5902 or other series variants. Consult official manufacturer notices for approved cross-reference options.
