ISO7240CFQDWRQ1

Overview

The ISO7240CFQDWRQ1 is a quad-channel digital isolator from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It features capacitive coupling technology to provide electrical isolation between circuits. The device supports a data rate of 25 Mbps and offers an insulation voltage of 4000 Vrms. It operates within a supply voltage range of 3.15 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a 16-SOIC format, it ensures reliable signal transmission in high-noise environments.

Feature Summary

• Automotive-grade qualification ensuring robust performance under strict reliability standards
• High common-mode transient immunity for accurate signal integrity in noisy systems
• Capacitive coupling isolation providing galvanic separation without magnetic interference

Applications

• Automotive engine control units requiring isolated communication
• Inverter gate drive circuits in electric vehicle powertrains
• Battery management system monitoring interfaces

Procurement Notes

Verify the specific suffix 'CFQDWRQ1' to confirm automotive grade and tape-and-reel packaging. Ensure compatibility with existing PCB footprints for the 16-SOIC package. Check for recent product change notifications regarding manufacturing site updates. Confirm that the component meets all required AEC-Q100 specifications for your target application environment.

Selection Notes

Select this component when automotive certification is mandatory for quad-channel isolation needs. It is suitable for designs requiring high common-mode transient immunity at moderate data rates. Consider thermal management requirements given the operating temperature range. Evaluate power consumption against system battery constraints if used in low-power automotive subsystems.

Part Context

This part belongs to the ISO7240 family of high-speed digital isolators. It shares the same core isolation architecture as other variants but includes specific automotive qualifications and packaging options. The 'Q1' suffix denotes its suitability for automotive electronics, distinguishing it from standard industrial versions within the broader Texas Instruments isolation portfolio.

Replacement Considerations

ISO7240CDWRQ1 serves as a direct functional substitute with identical pinout and specifications. Verify that any replacement maintains the same automotive qualification status and insulation voltage ratings to ensure system compliance.
