ISO6763QDWRQ1

Overview

The ISO6763QDWRQ1 is an automotive-grade digital isolator from Texas Instruments, designed for high-speed signal transmission in harsh environments. It features six channels with bidirectional data flow, supporting a data rate of 50 Mbps. The device utilizes capacitive coupling technology to provide robust isolation with an insulation voltage of 5000 Vrms. Operating within a supply voltage range of 1.71 V to 5.5 V, it exhibits a propagation delay of 11 ns and a power dissipation of 196 mW. Packaged in a SOIC-16 format, it functions reliably across temperatures from -40°C to +125°C.

Feature Summary

• Six-channel bidirectional architecture enables flexible signal routing between isolated domains.
• Capacitive coupling technology ensures reliable galvanic isolation without optical components.
• Automotive qualification supports operation in demanding thermal and electrical conditions.

Applications

• Automotive battery management systems requiring multi-channel isolation
• Inverter control circuits for electric vehicle powertrains
• On-board charger interfaces for high-voltage isolation

Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm AEC-Q100 qualification status if automotive reliability is mandatory. Check moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure ordering quantities align with manufacturer packaging standards to avoid handling discrepancies.

Selection Notes

Select this component when bidirectional communication is required across multiple isolated channels simultaneously. The 50 Mbps speed suits general-purpose applications where ultra-high bandwidth is unnecessary. Consider the SOIC-16 footprint for board space constraints. Evaluate power consumption against system thermal limits given the 196 mW dissipation rating.

Part Context

This part belongs to the ISO6763 series of automotive digital isolators. It complements unidirectional variants like the ISO6760 by offering bidirectional capability. The family shares similar isolation voltages and packaging but differs in channel directionality and count. It serves as a key interface solution for complex automotive electronic architectures.
