ISO7710QDQ1

Overview

The ISO7710QDQ1 is a single-channel digital isolator from Texas Instruments, designed for automotive applications with AEC-Q100 Grade 1 qualification. It operates within a temperature range of -40°C to +125°C and supports data rates up to 100 Mb/s. The device features capacitive coupling isolation with an insulation voltage of 3000 Vrms. It functions on a supply voltage between 2.25 V and 5.5 V, drawing a typical operating current of 5.9 mA. Key electrical parameters include a propagation delay of 11 ns, rise/fall times of 3.9 ns, and pulse width distortion of 0.6 ns. The component is housed in an SOIC-8 package.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Reinforced single-channel digital isolation using capacitive coupling technology
• High-speed signal transmission capability at 100 Mb/s data rates

Applications

• Automotive electronic control units requiring galvanic isolation
• Inverter gate drive circuits in electric vehicle powertrains
• Isolated communication interfaces in automotive sensor systems

Procurement Notes

Verify the specific suffix (DQ1 vs DWRQ1) as package variations exist. Confirm current manufacturing status, as some listings indicate obsolescence for this specific part number while recommending substitutes. Ensure the supplier provides valid traceability documentation for automotive grade components. Check for moisture sensitivity level requirements during storage and handling procedures before assembly.

Selection Notes

Select this component when a single-channel isolated interface is required for automotive environments. Compare against the ISO7710QDRQ1 if a different package configuration is preferred. Consider the 3000 Vrms insulation rating against system isolation requirements. Evaluate the 100 Mb/s speed limit against application bandwidth needs. Verify compatibility with the target logic voltage levels within the specified supply range.

Part Context

This device belongs to the ISO7710-Q1 family of high-speed digital isolators. It shares core electrical specifications with other variants in the series but differs in packaging and specific qualification markings. The family is engineered to provide robust electromagnetic compatibility performance in noisy automotive electrical environments while maintaining signal integrity across isolation barriers.

Replacement Considerations

Texas Instruments recommends the ISO7710QDRQ1 as a substitute. Verify pinout and package dimensions match the existing design footprint. Confirm that the replacement meets all original automotive qualification requirements.
