ISO6720FBQDRQ1

Overview

The ISO6720FBQDRQ1 is an automotive-grade, general-purpose dual-channel digital isolator manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide electrical isolation between circuits. The device features two independent channels with unidirectional signal transmission capability. Key electrical specifications include a data rate of 50 Mb/s and a common-mode transient immunity (CMTI) of 100 kV/µs. It operates within a supply voltage range of 1.71 V to 5.5 V and supports a maximum insulation voltage of 3000 Vrms. The component is housed in an 8-SOIC package with a width of 3.90 mm.

Feature Summary

• Provides robust galvanic isolation using capacitive coupling technology for reliable signal transmission across isolated boundaries.
• Designed for automotive applications with functional safety capabilities supported by comprehensive documentation.
• Features high common-mode transient immunity to maintain signal integrity in electrically noisy environments.

Applications

• Automotive gate driver interfaces
• Inverter control systems
• Motor drive isolation

Procurement Notes

Verify the specific suffix 'FBQDRQ1' to ensure correct packaging and automotive qualification status. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Check for moisture sensitivity level compliance if reflow soldering is planned. Ensure the order quantity aligns with the manufacturer's reel or cut-tape availability constraints.

Selection Notes

Select this component when dual-channel isolation is required for automotive power electronics. It is suitable for applications needing moderate data rates up to 50 Mb/s. Consider the 3000 Vrms insulation rating for basic isolation needs. Evaluate the 1.71 V to 5.5 V supply range compatibility with your system logic levels before finalizing the design.

Part Context

This part belongs to the ISO6720-Q1 family of digital isolators from Texas Instruments. It is specifically qualified for automotive use under AEC-Q100 standards. The device serves as a key interface component in modern electric vehicle architectures, enabling safe communication between low-voltage control units and high-voltage power stages.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISO672x series. Verify if higher CMTI or different channel configurations are needed. Ensure any substitute maintains the same automotive qualification and SOIC-8 package form factor.
