ADUM1301WTRWZ35

Overview

The ADUM1301WTRWZ35 is a digital isolator manufactured by Analog Devices Inc., featuring magnetic coupling technology. It provides three independent channels with a unidirectional configuration, specifically arranged as two transmitters and one receiver. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. Key electrical parameters include an isolation voltage of 2500 Vrms, a common-mode transient immunity of 25 kV/µs, and propagation delays of 32 ns. It is housed in a 16-SOIC package and is qualified under the AEC-Q100 standard for automotive applications.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal transmission without optical components.
• Provides robust galvanic isolation with high common-mode transient immunity.
• Features a unidirectional channel architecture optimized for specific directional data flow.
• Complies with AEC-Q100 standards for reliability in automotive environments.

Applications

• Automotive motor control systems requiring isolated gate drive signals
• Industrial communication interfaces such as CAN and LIN bus isolation
• Power electronics monitoring circuits needing high-voltage separation

Procurement Notes

Verify the specific suffix '35' against official manufacturer documentation to confirm package type or tape-and-reel specifications, as this variant may differ from standard tube packaging. Ensure compatibility with existing PCB footprints and reflow soldering profiles defined in the datasheet. Cross-reference the part number with current production status notices to avoid obsolete inventory risks.

Selection Notes

Select this component when a unidirectional 3-channel isolator with AEC-Q100 qualification is required. Compare performance metrics such as propagation delay and power consumption against alternative isolators if system timing constraints are tight. Consider the SOIC-16 footprint availability and thermal management requirements during the design phase.

Part Context

This part belongs to the ADUM1301 series of digital isolators from Analog Devices. It shares core architectural features with other members like the ADUM1301ARWZ but differs in packaging or manufacturing lot specifications indicated by the suffix. The series is designed for general-purpose isolation in noisy electrical environments.

Replacement Considerations

ADUM1301WTRWZ is listed as a parameter-equivalent replacement option. Verify that the functional specifications and pinout remain identical before substitution. Check for any differences in packaging or moisture sensitivity levels between the original and substitute parts.
