ISO7762QDBQQ1

Overview

The ISO7762QDBQQ1 is an automotive-grade, six-channel digital isolator from Texas Instruments, housed in a 16-SSOP package. It features four forward and two reverse channels with bidirectional or unidirectional polarity options. The device supports data rates up to 100 Mb/s and offers an insulation voltage of 5000 Vrms via capacitive coupling. Operating on a supply voltage range of 2.25 V to 5.5 V, it draws 25.7 mA of working power current. Key electrical parameters include a propagation delay of 11 ns, rise/fall times of 3.9 ns, and pulse width distortion of 0.4 ns. It functions within a temperature range of -40°C to +125°C and holds AEC-Q100 qualification.

Feature Summary

• Provides reinforced isolation rated at 5000 Vrms for robust electromagnetic compatibility in automotive environments.
• Integrates six independent channels (four forward, two reverse) to minimize board space and component count.
• Utilizes silicon dioxide-based capacitive coupling technology for high-speed signal transmission with low latency.
• Certified to multiple international safety standards including UL 1577, VDE, CSA, TUV, and CQC.

Applications

• Automotive gate driver circuits for electric vehicles and hybrid systems
• Inverter control modules requiring high-voltage isolation
• On-board charger (OBC) communication interfaces
• Battery management system (BMS) isolated data links

Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the DBQ package variant matches the required 5000 Vrms insulation rating rather than lower-rated alternatives. Confirm lead times and moisture sensitivity levels prior to ordering, as these components are sensitive to humidity during storage and handling processes.

Selection Notes

Select this component when designing systems requiring six isolated channels with high-speed performance up to 100 Mb/s. It is suitable for applications demanding reinforced insulation ratings and compliance with strict automotive EMC standards. Consider the 16-SSOP footprint constraints and verify that the 2.25 V to 5.5 V supply range aligns with the target logic voltage requirements.

Part Context

This part belongs to the ISO776x-Q1 family of high-performance digital isolators designed specifically for automotive applications. The series provides scalable channel configurations while maintaining consistent electrical characteristics across variants. It serves as a critical interface component between low-voltage control logic and high-voltage power stages in modern vehicle architectures.

Replacement Considerations

Direct substitutes within the same family include ISO7762QDBQRQ1, which shares identical electrical specifications but may differ in reel packaging configuration. Verify that any replacement maintains the same 5000 Vrms insulation rating and AEC-Q100 qualification level to ensure design continuity.
