ISO7730QDBQQ1

Overview

The ISO7730QDBQQ1 is an automotive-grade, reinforced triple-channel digital isolator from Texas Instruments. It features three unidirectional channels with a data rate of 100 Mb/s and a propagation delay of 11 ns. The device operates on a supply voltage range of 2.25 V to 5.5 V with a typical quiescent current of 17.5 mA per side. It provides an insulation voltage of 3000 Vrms and utilizes capacitive coupling technology. The component is housed in a 16-SSOP package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Reinforced isolation barrier for high safety integrity
• Robust electromagnetic compatibility performance
• High common-mode transient immunity

Applications

• Automotive engine control units
• Body electronics modules
• Infotainment system interfaces
• Battery management systems

Procurement Notes

Verify the specific suffix 'QQ1' against official Texas Instruments documentation to confirm it denotes the automotive grade variant with reinforced isolation ratings. Ensure the SSOP-16 package matches the design footprint requirements. Confirm that the 3000 Vrms insulation rating aligns with the safety isolation requirements of the target application circuit.

Selection Notes

Select this component when automotive reliability and reinforced isolation are required for signal transmission across potential barriers. It is suitable for designs needing three independent unidirectional channels with high-speed data rates up to 100 Mb/s. Consider the SSOP-16 package constraints and the 2.25 V to 5.5 V supply voltage range during schematic capture.

Part Context

This part belongs to the ISO7730 family of high-speed digital isolators. It is specifically designed for robust EMC environments found in automotive systems. The QDBQ suffix indicates the automotive grade and SSOP-16 package configuration, distinguishing it from industrial grade or SOIC package variants within the same series.

Replacement Considerations

Direct substitutes include ISO7730QDWRQ1 (SOIC-16 package) and ISO7730QDBQRQ1 (SSOP-16 package). Verify pinout compatibility and insulation voltage ratings before substitution.
