ADUM4402WBRWZ

Overview

The ADUM4402WBRWZ is a quad-channel digital isolator from Analog Devices, utilizing proprietary magnetic coupling technology for signal isolation. It features a 5000 Vrms insulation voltage rating and supports data rates up to 90 Mb/s. The device operates within a supply voltage range of 2.7 V to 5.5 V and includes enhanced ESD protection. It is housed in a 16-lead SOIC package with a 7.50 mm width, designed for surface mount installation. The component meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Proprietary magnetic coupling technology enables low-power signal isolation without the need for external transformer drive circuits.
• Enhanced ESD protection provides robust performance against electrostatic discharge events common in industrial environments.
• High common-mode transient immunity ensures reliable data transmission in electrically noisy systems.

Applications

• Industrial automation control systems requiring galvanic isolation
• Automotive electronics meeting AEC-Q100 reliability standards
• Medical equipment needing high-voltage isolation safety

Procurement Notes

Verify the specific suffix 'WBRWZ' to confirm the wide-body SOIC-16 package and reel packaging format. Confirm AEC-Q100 qualification status if used in automotive designs. Check current availability as distribution may be limited or subject to factory special orders. Ensure compatibility with your ECAD tool libraries before finalizing procurement.

Selection Notes

Select this component when high channel count (four channels) and moderate data rates are required. It is suitable for applications needing 5kV isolation with enhanced ESD resilience. Consider power consumption constraints as it offers low-power operation compared to optical isolators. Verify thermal management requirements for the SOIC-16 package in enclosed spaces.

Part Context

This part belongs to the ADUM4402 series of digital isolators. It serves as an alternative to optocouplers by offering smaller size and lower power consumption. The series is designed for general-purpose isolation in communication buses and gate drive applications.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADUM440x family. Verify that any replacement maintains the 5kV isolation rating and 90 Mb/s data rate. Ensure the alternative package matches the 16-SOIC form factor for board retention.
