ISO7710FQDWQ1

Overview

The ISO7710FQDWQ1 is an automotive-grade, single-channel digital isolator from the ISO7710-Q1 series by Texas Instruments. It utilizes capacitive coupling technology to provide galvanic isolation with a rated insulation voltage of 3000 Vrms. The device supports data rates up to 100 Mb/s and operates within a supply voltage range of 2.25 V to 5.5 V. Key electrical parameters include a typical propagation delay of 11 ns, a maximum power dissipation of 50 mW, and a working supply current of 5.9 mA. It is qualified to AEC-Q100 standards for automotive applications and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides reinforced electromagnetic compatibility (EMC) performance suitable for noisy automotive environments
• Features unidirectional signal transmission with a single channel configuration
• Utilizes robust capacitive coupling isolation architecture for high reliability

Applications

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

Procurement Notes

Verify the specific suffix 'DWQ1' corresponds to the SOIC-16 package and tape-and-reel or tube packaging as defined in the official datasheet. Confirm AEC-Q100 qualification status and RoHS compliance details directly from the manufacturer's documentation before procurement. Ensure the component meets the required thermal and electrical specifications for the target automotive application environment.

Selection Notes

Select this component when a single-channel, high-speed digital isolator with automotive certification is required. It is appropriate for designs needing 3000 Vrms isolation strength and 100 Mb/s data throughput. Consider the SOIC-16 footprint and 2.25 V to 5.5 V supply range during PCB layout and power budgeting. Compare against other ISO7710 variants if different channel counts or package types are needed.

Part Context

This part belongs to the ISO7710-Q1 family of automotive digital isolators. It shares the core capacitive isolation technology with other members like the ISO7710FQDRQ1 but differs in package type and insulation voltage ratings. The ISO7710 series is designed to replace magnetic couplers in automotive networks, offering smaller size and lower power consumption while maintaining high common-mode transient immunity.
