ISO6720BQDRQ1

Overview

The ISO6720BQDRQ1 is an automotive-grade, general-purpose dual-channel digital isolator from Texas Instruments. It features a 2/0 channel configuration with unidirectional signal paths and supports 1.8V logic levels. The device operates within a supply voltage range of 1.7 V to 5.5 V and delivers a data rate of 50 Mb/s. Key electrical parameters include a propagation delay of 11 ns, an insulation voltage of 5000 Vrms, and a common-mode transient immunity of 100 kV/µs. It functions reliably across a temperature range of -40°C to +125°C and is housed in an SOIC-8 package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust reliability in vehicle environments
• Capacitive coupling technology providing reinforced and basic isolation capabilities
• Functional safety capable design supporting system-level safety documentation requirements

Applications

• Automotive gateway systems requiring isolated communication interfaces
• Inverter control circuits in electric and hybrid vehicles
• Battery management systems needing high-voltage isolation
• On-board charger (OBC) signal isolation

Procurement Notes

Verify the specific suffix 'B' indicates the correct revision level required for your design. Confirm that the SOIC-8 package dimensions match your PCB footprint constraints. Ensure the component meets the specific AEC-Q100 grade requirements for your target automotive application zone. Cross-reference the datasheet version to confirm compatibility with existing firmware or hardware designs.

Selection Notes

Select this component when an automotive-rated, dual-channel isolator with unidirectional flow is needed. It is suitable for applications requiring 50 Mbps data rates and 5000 Vrms isolation. Consider the 1.8V logic support if interfacing with low-voltage microcontrollers. The SOIC-8 package offers a compact solution for space-constrained automotive boards compared to wider packages.

Part Context

This part belongs to the ISO672x-Q1 family of automotive digital isolators. It shares the same core isolation architecture as the ISO6721-Q1 but differs in channel directionality. The ISO6720 variant provides two inputs and zero outputs, whereas other family members may offer bidirectional or different channel counts. This family is designed to replace magnetic isolators in automotive networks.

Replacement Considerations

The ISO6720BDQRQ1 is a non-automotive equivalent with similar specifications but lacks AEC-Q100 certification. For direct automotive replacements, verify availability of the ISO6720BQDRQ1 itself. Other TI isolators like the ISO7720QDRQ1 offer higher performance metrics but may require design adjustments.
