ADUM5403WCRWZ-1RL

Overview

The ADUM5403WCRWZ-1RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isolated DC-to-DC converter. It utilizes iCoupler technology for magnetic coupling isolation with a rated insulation voltage of 2500 Vrms and a common-mode transient immunity of 25 kV/µs. The device supports data rates up to 25 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. It is housed in a 16-pin SOIC-W package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates a regulated isolated power supply delivering up to 500 mW at 5.0 V
• Provides four independent signal channels with configurable directionality
• Employs proprietary iCoupler magnetic coupling technology for high-speed isolation

Applications

• Automotive gate driver interfaces
• Industrial fieldbus communication nodes
• Isolated power supply control circuits

Procurement Notes

Verify the specific suffix '1' against official Analog Devices documentation to confirm pinout configuration and directionality settings, as this variant differs from standard models. Ensure compatibility with the required isolation voltage ratings and thermal management requirements for the target application environment before finalizing procurement.

Selection Notes

Select this component when a single IC solution is required to provide both signal isolation and isolated power generation, eliminating the need for external isolated power supplies. Consider the 2500 Vrms insulation rating and 25 kV/µs CMTI for robust noise immunity in electrically noisy industrial or automotive environments requiring high reliability.

Part Context

This part belongs to the ADuM540x family of quad-channel digital isolators. It is distinct from the ADUM5401 and ADUM5402 variants primarily through its specific channel directionality configuration and integrated power output capabilities. The WCRWZ-1RL designation indicates a wide-body SOIC package, reel packaging, and specific automotive qualification status.

Replacement Considerations

Direct substitutes include the ADUM5403CRWZ-RL and ADUM5403WCRWZ-1. Verify that alternative packages or reel quantities meet mechanical and manufacturing constraints without altering functional specifications.
