ISO6762QDWRQ1

Overview

The ISO6762QDWRQ1 is an automotive-grade digital isolator from Texas Instruments, featuring six channels with bidirectional data flow. It utilizes capacitive coupling technology to provide electrical isolation rated at 5000 Vrms. The device supports a data rate of 50 Mb/s and operates within a supply voltage range of 1.71 V to 5.5 V. Key performance metrics include a propagation delay of 11 ns, rise and fall times of 4.5 ns, and a pulse width distortion of 7 ns. It functions reliably across a temperature range of -40°C to +125°C and is housed in a SOIC-16 package.

Feature Summary

• Provides galvanic isolation via capacitive coupling technology for robust signal transmission.
• Supports bidirectional data transfer across all six internal channels.
• Certified for automotive applications under AEC-Q100 standards.
• Operates with low power consumption suitable for energy-efficient designs.

Applications

• Automotive battery management systems
• Inverter control circuits
• Motor drive interfaces

Procurement Notes

Verify the component authenticity by checking the manufacturer's part marking against official datasheet specifications. Confirm that the suffix QDWRQ1 corresponds to the automotive qualification, SOIC-16 package, and tape-and-reel packaging format. Ensure compliance with moisture sensitivity levels as indicated in the handling guidelines prior to assembly.

Selection Notes

Select this component when bidirectional communication is required between isolated domains in automotive environments. It is suitable for applications needing high channel density in a single package. Consider the 5000 Vrms isolation rating for safety-critical interfaces. Evaluate power budget constraints against the specified operating current before finalizing the design.

Part Context

This device belongs to the ISO676x family of automotive digital isolators. It shares the SOIC-16 footprint and capacitive isolation architecture with other members like the ISO6760QDWRQ1. Unlike unidirectional variants, this model specifically enables two-way data exchange, distinguishing it within the series for complex control loop applications.

Replacement Considerations

The ISO6760QDWRQ1 serves as a functional substitute if unidirectional channels suffice. Verify pin compatibility and isolation ratings when swapping components to ensure system integrity without redesigning the PCB layout.
