ISO7710FQDWRQ1

Overview

The ISO7710FQDWRQ1 is a single-channel reinforced digital isolator from Texas Instruments, designed for automotive applications. It features capacitive coupling technology with a data rate of 100 Mb/s and an insulation voltage of 5000 Vrms. The device operates within a supply voltage range of 2.25 V to 5.5 V, consuming 5.9 mA of quiescent current. It exhibits a propagation delay of 11 ns and rise/fall times of 3.9 ns. Packaged in a 16-SOIC (0.295 inch width), it supports unidirectional signal transmission. The component is qualified under AEC-Q100 Grade 1, ensuring reliability across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides reinforced isolation capabilities suitable for demanding automotive environments
• Utilizes high-speed capacitive coupling for reliable signal transmission at 100 Mb/s
• Ensures robust electromagnetic compatibility performance for system stability

Applications

• Automotive electronic control units requiring galvanic isolation
• Inverter gate drive circuits in electric vehicle powertrains
• On-board charging systems for isolated communication interfaces

Procurement Notes

Verify the specific suffix 'FQDWRQ1' to confirm the 16-pin SOIC package and 5000 Vrms insulation rating. Ensure the order specifies the 'R' reel packaging variant if required for automated assembly processes. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when a single-channel solution with high insulation voltage is required for automotive systems. It is appropriate for designs needing 100 Mb/s data rates with low propagation delay. Consider the 16-SOIC footprint for board space constraints. Verify that the 2.25 V to 5.5 V supply range aligns with the target logic levels and power budget.

Part Context

This device belongs to the ISO7710-Q1 family of automotive-grade digital isolators. It shares core specifications with the ISO7710QDWRQ1 but differs in package type and insulation voltage ratings compared to other variants like the ISO7710FQDRQ1. The family is characterized by its robust EMC performance and compliance with strict automotive reliability standards.

Replacement Considerations

The ISO7710QDWRQ1 serves as a direct functional substitute within the same series, offering identical electrical characteristics and channel configuration.
