ISO6760FQDWRQ1

Overview

The ISO6760FQDWRQ1 is an automotive-grade digital isolator from Texas Instruments, featuring six unidirectional channels with capacitive coupling. It supports data rates up to 50 Mb/s and provides galvanic isolation with a rated insulation voltage of 5000 Vrms. The device operates within a supply voltage range of 1.71 V to 5.5 V and draws a typical quiescent current of 21.9 mA. It exhibits a propagation delay of 11 ns and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a 16-pin SOIC (DW) format, it meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Six-channel unidirectional signal isolation using robust capacitive coupling technology
• High-speed data transmission capability supporting up to 50 Mbps per channel
• Extended industrial temperature operation suitable for demanding automotive environments
• Automotive qualification ensuring reliability under strict industry standards

Applications

• Automotive battery management systems requiring isolated communication
• Inverter control circuits in electric vehicle powertrains
• On-board charger interfaces needing high-voltage isolation
• General-purpose automotive electronic control units

Procurement Notes

Verify the complete part number including suffixes to ensure correct package and tape-and-reel specifications. Confirm that the component carries the Q1 designation for automotive grade compliance. Check datasheet revision dates to align with latest electrical characteristics. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when six independent unidirectional isolation paths are required in space-constrained designs. The low input capacitance and high common-mode transient immunity make it suitable for noisy automotive environments. Compare total system power consumption against alternatives if battery efficiency is critical. Ensure the 5000 Vrms isolation rating matches the circuit's safety requirements.

Part Context

This device belongs to the ISO676x-Q1 family of automotive digital isolators. It complements other variants like the ISO6762 which offers bidirectional channels. The family shares similar packaging and interface characteristics but varies in channel count and directionality. It serves as a key interface solution between low-voltage logic and high-voltage power stages in modern vehicles.

Replacement Considerations

Direct replacements include ISO6760FQDR or non-automotive ISO6760FQD. Verify pin compatibility and isolation ratings before substitution. Consider ISO6762FQDWRQ1 if bidirectional functionality is needed instead of unidirectional.
