ISO7763QDBQQ1

Overview

The ISO7763QDBQQ1 is a six-channel digital isolator from the ISO776x-Q1 series, designed for automotive applications. It features a 5/1 channel configuration with unidirectional signal flow. The device utilizes capacitive coupling technology to provide reinforced isolation with a rated insulation voltage of 3000 Vrms. It supports data rates up to 100 Mb/s and offers a common-mode transient immunity of 85 kV/µs. Operating within a supply voltage range of 2.25 V to 5.5 V, it functions reliably across an extended temperature range of -40°C to +125°C. The component is housed in a 16-SSOP package and holds AEC-Q100 qualification.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for robust reliability in vehicle environments.
• Reinforced isolation capability providing high electrical safety margins between isolated circuits.
• High-speed data transmission supporting 100 Mb/s rates with low propagation delay characteristics.
• Superior electromagnetic compatibility performance ensured by high common-mode transient immunity.

Applications

• Automotive gateway systems requiring multi-channel signal isolation
• Inverter control units for electric vehicles
• Body control modules (BCM) with CAN bus interfaces
• Battery management systems (BMS) communication networks

Procurement Notes

Verify the specific suffix 'QQ1' indicates tube packaging, distinct from 'QRQ1' which denotes tape and reel formats. Confirm that the part number corresponds to the 5-input/1-output channel configuration rather than other variants in the ISO7763 family. Ensure compliance with RoHS directives and check for moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Selection Notes

Select this component when a six-channel isolator with a 5/1 split is required for automotive designs. It is suitable for applications needing 3000 Vrms reinforced isolation and 100 Mb/s data throughput. Consider the SSOP-16 package constraints and verify power supply voltage compatibility within the 2.25 V to 5.5 V range against system specifications.
