ISO7762QDWQ1

Overview

The ISO7762QDWQ1 is a six-channel digital isolator from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It features capacitive coupling technology and operates within a -40°C to +125°C temperature range. The device provides 5000 Vrms isolation voltage and supports data rates up to 100 Mbps. It includes four forward and two reverse channels in a 16-pin SOIC package.

Feature Summary

• Automotive-grade robustness with EMC immunity
• Six-channel bidirectional or unidirectional isolation
• High common-mode transient immunity

Applications

• Automotive electronic control units
• Industrial communication interfaces
• Isolated gate driver circuits

Procurement Notes

Verify the specific suffix (QDW vs QDWR) against the datasheet to confirm packaging type, as the QDW variant typically indicates tube packaging while QDWR indicates reel. Confirm current manufacturing status, as this part may be obsolete or superseded by newer revisions. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when six isolated channels are required in a single package for space-constrained designs. Consider the 100 Mbps data rate and propagation delay specifications relative to system timing requirements. Verify that the 5000 Vrms isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the ISO77xx-Q1 family of automotive digital isolators. It shares architectural similarities with other members like the ISO7742QDWRQ1 but offers a different channel count configuration. The family utilizes Texas Instruments' capacitive isolation technology for high reliability.

Replacement Considerations

Check for ISO7762QDWRQ1 if tape-and-reel packaging is preferred over tubes. Verify if the ISO7763QDWRQ1 is suitable for applications requiring three forward and three reverse channels instead of four and two.
