ISO7331CQDWQ1

Overview

The ISO7331CQDWQ1 is an automotive-grade, low-power, triple-channel digital isolator from Texas Instruments. It features a SOIC-16 (DW) package and operates within a supply voltage range of 3 V to 5.5 V. The device supports unidirectional data transmission at speeds up to 25 Mb/s with a typical propagation delay of 36 ns. It provides 3000 Vrms isolation via capacitive coupling and is qualified under AEC-Q100 standards for operation between -40°C and +125°C.

Feature Summary

Triple-channel configuration for multi-signal isolation
Automotive qualification ensuring reliability in harsh environments
Low power consumption suitable for energy-efficient designs
Robust electromagnetic compatibility performance

Applications

Automotive electronic control units
Inverter gate drive circuits
On-board charging systems
Battery management systems

Procurement Notes

Verify the specific suffix Q1 confirms AEC-Q100 automotive qualification. Ensure the DW package variant matches the required PCB footprint. Confirm that the unidirectional channel orientation aligns with the system signal flow requirements before finalizing procurement.

Selection Notes

Select this component when three isolated channels are required for automotive applications. It is suitable for designs needing moderate data rates up to 25 Mbps. Consider the SOIC-16 package constraints and thermal dissipation capabilities within the specified temperature range during layout planning.

Part Context

This part belongs to the ISO733x-Q1 family of robust, low-power digital isolators. It shares core technology with other variants in the series but offers a specific triple-channel configuration. The family is designed to meet stringent automotive EMC and reliability standards while maintaining low power profiles.

Replacement Considerations

Check for ISO7330CQDWQ1 if bidirectional communication is required instead of unidirectional. Verify pinout compatibility with existing designs when substituting with other members of the ISO733x-Q1 family.
