ISO7763QDWRQ1

Overview

The ISO7763QDWRQ1 is a six-channel digital isolator from Texas Instruments, designed for automotive robustness and EMC performance. It features a 3/3 channel configuration with bidirectional or unidirectional polarity options. The device operates on a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 100 Mb/s. It provides an insulation voltage of 5000 Vrms using capacitive coupling technology. Key electrical parameters include a propagation delay of 11 ns, a maximum power dissipation of 292 mW, and a typical operating supply current of 21 mA. It is qualified under AEC-Q100 standards and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Six-channel isolation architecture supporting flexible 3/3 channel configurations
• Automotive-grade qualification ensuring robust electromagnetic compatibility (EMC) performance
• High common-mode transient immunity capability for reliable signal integrity in noisy environments

Applications

• Automotive electronic control units requiring high-speed isolated communication
• Industrial automation systems needing robust galvanic isolation
• Power conversion circuits utilizing isolated gate drive signals

Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the 'DW' package designation matches the required SOIC-16 footprint dimensions. Confirm that the selected variant aligns with the necessary channel directionality (unidirectional vs. bidirectional) for the target circuit design before finalizing orders.

Selection Notes

Select this component when a high-density six-channel solution is required for automotive applications. It is suitable for designs demanding 100 Mb/s data throughput with significant isolation voltage requirements. Consider the 2.25 V to 5.5 V supply range compatibility with existing logic levels. Evaluate the thermal performance given the 292 mW power dissipation limit in enclosed enclosures.

Part Context

This part belongs to the ISO7763 family of digital isolators, which are engineered for high reliability in harsh environments. The series utilizes capacitive coupling technology to provide isolation without magnetic components. The Q1 suffix specifically denotes automotive grade qualification, distinguishing it from standard industrial variants within the same functional family.

Replacement Considerations

The ISO7763QDBQRQ1 serves as a pin-compatible alternative in the SSOP-16 package format. Both parts share identical electrical specifications and channel configurations. Verify package dimension constraints before substituting between SOIC and SSOP footprints.
