ISO7320FCQDRQ1

Overview

The ISO7320FCQDRQ1 is an automotive-grade, low-power, dual-channel digital isolator manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide electrical isolation between circuits. The device features a unidirectional signal path with two forward channels and zero reverse channels. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. Key electrical specifications include a typical propagation delay of 32 ns, an insulation voltage of 3000 Vrms, and a common-mode transient immunity of 25 kV/µs. The component is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
• Low power consumption design suitable for energy-efficient systems
• Robust electromagnetic compatibility (EMC) performance
• High common-mode transient immunity for noise-resistant signal transmission

Applications

• Automotive electronic control units requiring isolated communication
• In-vehicle networking interfaces
• Battery management systems
• Charging station controllers

Procurement Notes

Verify the specific suffix 'QDRQ1' to confirm the automotive grade, SOIC-8 package, and tape-and-reel packaging configuration. Ensure the order matches the exact part number to avoid confusion with non-automotive variants or different package styles such as tubes. Confirm compliance with RoHS directives and humidity sensitivity levels prior to procurement.

Selection Notes

Select this component when automotive certification is mandatory for digital isolation applications. It is appropriate for designs requiring unidirectional signal transfer with moderate data rates. Consider the SOIC-8 footprint constraints and the 3 V to 5.5 V supply requirement during circuit planning. Evaluate the 25 kV/µs CMTI rating against the noise environment of the target application.
