ISO7730QDWQ1

Overview

The ISO7730QDWQ1 is an automotive-grade digital isolator from the ISO7730 series, manufactured by Texas Instruments. It features three independent channels with unidirectional signal transmission using capacitive coupling technology. The device operates within a wide temperature range of -40°C to +125°C and supports data rates up to 100 Mb/s. Key electrical specifications include an insulation voltage of 5000 Vrms, a typical propagation delay of 11 ns, and a supply current of 17.5 mA. It is housed in a 16-pin SOIC package and holds AEC-Q100 qualification for robustness in demanding environments.

Feature Summary

• Automotive-qualified robust EMC performance ensuring reliable operation in electrically noisy vehicle environments
• Triple-channel architecture providing isolated signal paths for complex system integration
• Capacitive coupling isolation technology offering high reliability and long-term stability

Applications

• Automotive electronic control units requiring galvanic isolation
• Inverter gate drive circuits in electric vehicles
• On-board charging systems for hybrid and electric vehicles

Procurement Notes

Verify the specific suffix Q1 against the manufacturer's official datasheet to confirm it denotes the tube packaging variant, as the WRQ1 suffix typically indicates tape and reel. Ensure the component meets the required AEC-Q100 grade and that the SOIC-16 package dimensions align with your PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when three isolated channels are required for automotive applications with high electromagnetic interference immunity. Compare against the ISO7730QDWRQ1 if tape-and-reel packaging is preferred for automated assembly. Consider the ISO7720QDWRQ1 if only two channels are needed, or the ISO7763QDWRQ1 for six-channel requirements, while maintaining the same isolation voltage and speed specifications.

Part Context

This part belongs to the ISO7730 family of automotive digital isolators designed for high-speed data transmission across isolation barriers. It complements other members like the dual-channel ISO7720 and quad-channel ISO7740 variants, all sharing similar capacitive isolation technology but differing in channel count and packaging options to suit various board space and connectivity needs.

Replacement Considerations

The ISO7730QDWRQ1 serves as the direct tape-and-reel equivalent. Verify pinout compatibility with legacy designs before substitution.
