ADUM5201WCRWZ

Overview

The ADUM5201WCRWZ is a two-channel digital isolator from Analog Devices, featuring an integrated DC/DC converter for isolated power supply. It utilizes magnetic coupling technology to provide electrical isolation with a rated insulation voltage of 2500 Vrms. The device supports unidirectional data transmission at speeds up to 25 Mb/s with a propagation delay of 60 ns. It operates within a supply voltage range of 3 V to 5.5 V and is qualified under the AEC-Q100 automotive standard. The component is housed in a 16-lead SOIC package and is designed for operation across an extended temperature range from -40°C to +105°C.

Feature Summary

• Integrates a high-efficiency DC/DC converter to generate isolated power, eliminating the need for external isolated supplies.
• Employs iCoupler magnetic coupling technology to achieve robust signal isolation without optical components.
• Meets AEC-Q100 qualification standards for automotive electronic applications requiring high reliability.

Applications

• Automotive battery management systems
• Industrial motor control interfaces
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix WCRWZ against official Analog Devices documentation to confirm the reel packaging configuration and RoHS compliance status. Ensure that the AEC-Q100 qualification is active for this specific part number variant. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when bidirectional isolation is not required, as it supports only unidirectional channels. The integrated DC/DC converter simplifies board layout by providing isolated power but requires careful consideration of thermal management due to internal power dissipation. Verify that the 2500 Vrms isolation rating meets the safety requirements of the target application environment.

Part Context

This part belongs to the ADUM5201 series of IsoPower digital isolators. It shares the same core architecture and pinout with other variants in the family, differing primarily in packaging options and specific qualification levels. The series is designed to replace traditional optocouplers in applications demanding higher bandwidth and better performance consistency.

Replacement Considerations

Direct replacements include ADUM5201WCRWZ-RL for identical reel specifications. For tube packaging, consider ADUM5201WCRWZ. Higher isolation variants such as ADUM6201 offer 5000 Vrms isolation with similar functionality.
