ADUM5401WCRWZ-1

Overview

The ADUM5401WCRWZ-1 is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC/DC converter. It utilizes iCoupler magnetic coupling technology to provide four independent signal channels with unidirectional polarity. The device supports data rates up to 25 Mb/s and offers high common-mode transient immunity of 25 kV/µs. It operates within a supply voltage range of 3 V to 5.5 V and delivers up to 500 mW of regulated isolated power. The component is housed in a 16-lead SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates an isoPower isolated DC/DC converter providing up to 500 mW of regulated output power without external components.
• Employs iCoupler chip-scale transformer technology to isolate logic signals, power, and feedback paths within a compact form factor.
• Features four independent unidirectional signal channels capable of supporting data rates up to 25 Mb/s.
• Delivers high robustness with a minimum common-mode transient immunity of 25 kV/µs.

Applications

• Isolated gate drive circuits for power electronics
• Industrial fieldbus isolation interfaces
• Isolated sensor interface systems
• Power supply bias and control loops

Procurement Notes

Verify the specific suffix '-1' indicates AEC-Q100 qualification when sourcing. Confirm package orientation and pinout compatibility during integration. Check current availability status as supply may be restricted. Ensure PCB layout adheres to AN-0971 guidelines for electromagnetic compliance due to the integrated switching converter.

Selection Notes

Select this part for designs requiring both signal isolation and a regulated isolated power source in a single package. It is suitable for applications needing AEC-Q100 qualification. Compare against non-isolated-power variants like the ADUM5401 if external power management is preferred. Consider the 16-SOIC footprint constraints and thermal dissipation requirements for the integrated converter.

Part Context

This component belongs to the ADuM540x family of quad-channel digital isolators. It distinguishes itself by integrating the isoPower technology, eliminating the need for separate isolated DC/DC converters. This integration reduces board space and simplifies design complexity compared to traditional multi-component isolation solutions.

Replacement Considerations

The ADUM5401WXRWZ is listed as a discontinued equivalent or predecessor variant. Verify functional equivalence and availability before substitution. Other family members like the ADUM5401CRWZ lack the integrated power converter and are not direct replacements for power-supplying applications.
