ISO6721FQDWVRQ1

Overview

The ISO6721FQDWVRQ1 is an automotive-grade, dual-channel digital isolator from Texas Instruments, designed for general-purpose applications. It features capacitive coupling technology with a 5000 Vrms isolation voltage and supports data rates up to 50 Mb/s. The device operates within a supply voltage range of 1.71 V to 5.5 V and maintains functionality across a temperature range of -40°C to +125°C. Packaged in an 8-pin SOIC (DW) format, it offers unidirectional signal transmission with a typical propagation delay of 11 ns and a common-mode transient immunity of 100 kV/µs.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
• High common-mode transient immunity of 100 kV/µs ensures robust signal integrity in noisy systems
• Capacitive coupling architecture provides reinforced and basic isolation capabilities
• Supports wide supply voltage ranges enabling compatibility with various logic levels

Applications

• Automotive gate driver circuits

• Motor drive interfaces
• On-board charging systems

Procurement Notes

Verify the Q1 suffix confirms AEC-Q100 automotive qualification status. Ensure the DWVR package variant matches the required SOIC-8 footprint and reel specifications. Confirm functional safety compliance requirements align with specific application needs before finalizing procurement orders.

Selection Notes

Select this component when high-speed digital isolation is required in automotive environments. The dual-channel configuration suits applications needing independent signal paths. Consider the 50 Mbps data rate limit and 11 ns propagation delay for timing-sensitive designs. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the ISO672x-Q1 family of general-purpose digital isolators. It shares architectural similarities with other members but is distinctively qualified for automotive use. The series emphasizes cost-effective isolation solutions with robust performance metrics suitable for mass production in vehicle electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISO6721 family that may offer different channel counts or isolation voltages. Verify that any substitute maintains the same SOIC-8 package dimensions and electrical characteristics to ensure seamless integration without board redesign.
