ISO7720QDWRQ1

Overview

The ISO7720QDWRQ1 is a dual-channel digital isolator from Texas Instruments, designed for automotive robust EMC applications. It features capacitive coupling technology with a 5000 VRMS insulation voltage rating. The device supports data rates up to 100 Mb/s and operates within a supply voltage range of 2.25 V to 5.5 V. Key electrical parameters include a propagation delay of 17 ns, rise/fall times of 3.9 ns, and a typical operating supply current of 11.6 mA. It is housed in a 16-pin SOIC package and meets AEC-Q100 Grade 1 qualification for temperatures ranging from -40°C to +125°C.

Feature Summary

• Automotive-grade qualification ensuring reliability under harsh environmental conditions
• High electromagnetic compatibility (EMC) robustness for stable signal transmission
• Capacitive isolation technology providing galvanic barrier without magnetic components

Applications

• Automotive body control modules requiring isolated communication
• Infotainment systems needing high-speed data isolation
• Sensor interfaces in electric vehicle powertrains

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade status and AEC-Q100 compliance. Ensure the 'DW' package variant matches the required 5000 VRMS isolation rating rather than lower-rated alternatives. Confirm moisture sensitivity level handling procedures are followed during assembly due to the SMD nature of the component.

Selection Notes

Select this component when dual-channel isolation is required for automotive networks with moderate speed demands. It is suitable for replacing legacy optocouplers where size reduction and higher reliability are priorities. Consider the 16-pin SOIC footprint for PCB layout compatibility with existing designs requiring unidirectional signal paths.

Part Context

This part belongs to the ISO772x-Q1 family of digital isolators. These devices are engineered to replace bulky optical couplers in automotive systems. The series emphasizes low power consumption and high noise immunity, making it a standard choice for modern vehicle electronics that demand strict safety and performance standards.

Replacement Considerations

Check pinout compatibility if substituting with other ISO772x variants. Verify that alternative parts meet the same AEC-Q100 Grade 1 temperature rating and 5000 VRMS isolation requirements for direct replacement in certified automotive assemblies.
