ISO7761FQDWQ1

Overview

The ISO7761FQDWQ1 is a Texas Instruments automotive-grade digital isolator featuring six channels with a 3/1 input/output configuration. It utilizes capacitive coupling technology to provide reinforced isolation of 5000 Vrms. The device supports data rates up to 100 Mbps and offers a common-mode transient immunity (CMTI) of 85 kV/µs. Operating on a supply voltage range of 2.25 V to 5.5 V, it functions within a temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC (0.295 inch width), it meets AEC-Q100 qualification standards for robust EMC performance.

Feature Summary

• Provides reinforced galvanic isolation via capacitive coupling technology
• Ensures high noise immunity with 85 kV/µs common-mode transient rejection
• Supports high-speed data transmission at rates up to 100 Mbps
• Qualified for automotive applications under AEC-Q100 standards

Applications

• Automotive electronic control units requiring signal isolation
• Inverter gate drive circuits in electric vehicles
• On-board charging systems for isolated communication
• Battery management system sensor interfaces

Procurement Notes

Verify the specific suffix 'DWQ1' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component holds valid AEC-Q100 certification for the target automotive grade. Ensure the 16-SOIC footprint matches the design layout constraints. Check for RoHS compliance status against current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when six isolated channels are necessary within a single package to save board space. Choose this part if the application demands high CMTI ratings above 50 kV/µs to prevent false triggering in noisy environments. Consider this device for designs operating between 2.25 V and 5.5 V where low propagation delay is critical for timing-sensitive signals.

Part Context

This device belongs to the ISO776x-Q1 family of high-speed digital isolators from Texas Instruments. It shares the same core architecture as other members like the ISO7761FQDBQRQ1 but differs in package type and channel configuration. The family is designed specifically for automotive electronics requiring robust electromagnetic compatibility and reliable signal integrity across harsh operating conditions.

Replacement Considerations

The ISO7761FQDWRQ1 serves as a recommended manufacturer substitute offering identical electrical specifications. Verify pin-to-pin compatibility and ensure the replacement maintains the same 16-SOIC package dimensions. Confirm that any alternative parts also meet AEC-Q100 automotive qualification requirements.
