ISO7710QDWRQ1

Overview

The ISO7710QDWRQ1 is a single-channel automotive-grade digital isolator from Texas Instruments, designed for robust electromagnetic compatibility (EMC) performance. It operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 100 Mb/s. The device features an insulation voltage of 5000 Vrms and a common-mode transient immunity of 85 kV/µs. Packaged in a 16-pin SOIC with a 7.50 mm width, it exhibits a typical propagation delay of 11 ns and consumes 5.9 mA of quiescent current. It functions unidirectionally and meets AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Feature Summary

• Provides enhanced isolation capabilities with high common-mode transient immunity for reliable signal transmission in noisy environments.
• Optimized for automotive applications with robust EMC performance and compliance with strict reliability standards.
• Utilizes capacitive coupling technology to achieve galvanic isolation without magnetic core limitations.

Applications

• Automotive engine control units requiring isolated communication interfaces
• Inverter gate drive circuits in electric vehicle powertrains
• Battery management systems needing isolated data acquisition channels

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm that the 'Q1' designation aligns with your project's automotive qualification requirements. Ensure the SOIC-16 footprint matches your PCB layout constraints. Cross-reference the datasheet revision date to confirm parameter accuracy against your design specifications.

Selection Notes

Select this component when a single channel of high-speed digital isolation is required in space-constrained automotive designs. The 7.50 mm SOIC package offers a compact solution compared to wider standard SOIC options. Consider the 100 Mb/s data rate limit and 85 kV/µs CMTI specification to ensure compatibility with your system's noise environment and speed requirements.

Part Context

This part belongs to the ISO7710-Q1 family of automotive digital isolators. It shares the same functional architecture as non-automotive variants but includes extended temperature ranges and rigorous testing protocols mandated by AEC-Q100 standards. The QDWRQ1 designation specifically identifies the single-channel, reel-packaged version in the SOIC-16 package.

Replacement Considerations

ISO7710QDWQ1 is the tape-and-reel alternative to the R-suffix version. ISO7710 is the non-automotive commercial grade equivalent, lacking the extended qualification data. Verify pinout compatibility before substituting with other single-channel isolators from different manufacturers.
