ISO7730FQDWRQ1

Overview

The ISO7730FQDWRQ1 is an automotive-grade, triple-channel digital isolator from Texas Instruments. It features reinforced insulation with a 5000 Vrms isolation rating and supports data rates up to 100 Mbps. The device provides 85 kV/µs common-mode transient immunity (CMTI) and operates within a supply voltage range of 2.25 V to 5.5 V. Packaged in a 16-pin SOIC (DW) with a 7.50 mm width, it is AEC-Q100 qualified for temperatures ranging from -40°C to +125°C.

Feature Summary

• Automotive qualification under AEC-Q100 standards for robust reliability
• Reinforced insulation providing high-voltage safety isolation
• High common-mode transient immunity for noise-sensitive environments

Applications

• Automotive gate driver circuits
• Inverter control systems
• On-board charging (OBC) interfaces

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade status and 'DW' indicates the 16-pin SOIC package. Ensure the datasheet matches the required 5000 Vrms reinforced isolation rating. Confirm the operating temperature range aligns with system thermal constraints. Validate that the 100 Mbps data rate meets signal integrity requirements for the intended application.

Selection Notes

Select this component when reinforced isolation is mandatory for safety compliance in automotive power electronics. The triple-channel configuration suits applications requiring simultaneous isolation of multiple signals, such as phase currents or gate drive feedback. Consider the 16-pin SOIC footprint for PCB layout compatibility. Verify that the 85 kV/µs CMTI is sufficient for the switching speeds of the target power devices.

Part Context

This part belongs to the ISO7730-Q1 family of automotive digital isolators. It utilizes capacitive coupling technology to transmit digital signals across an isolation barrier. The series is designed to replace bulky magnetic couplers in modern automotive architectures, offering smaller form factors and higher reliability.

Replacement Considerations

Check for ISO7730FQDWRQ1 equivalents with identical pinouts and insulation ratings. Verify if alternative parts meet the same AEC-Q100 qualification level. Ensure substitute components support the required 100 Mbps data rate and 5000 Vrms isolation voltage.
