ISO7710QDRQ1

Overview

The ISO7710QDRQ1 is a single-channel digital isolator from the ISO7710-Q1 family, designed for automotive applications. It features capacitive coupling technology with a 3000 Vrms isolation rating per UL 1577. The device supports data rates up to 100 Mb/s and operates within a supply voltage range of 2.25 V to 5.5 V. Key electrical parameters include a propagation delay of 11 ns, typical power consumption of 5.9 mA, and an operating temperature range from -40°C to +125°C. It is housed in an SOIC-8 package.

Feature Summary

• Automotive-grade robustness with EMC performance suitable for harsh environments
• High-speed signal transmission capability via capacitive coupling
• Enhanced safety isolation meeting UL 1577 standards

Applications

• Automotive electronic control units (ECUs)
• Isolated communication interfaces in vehicle networks
• Power management systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'QDRQ1' corresponds to the SOIC-8 package and 3000 Vrms rating, distinct from the DW variant. Confirm AEC-Q100 qualification status for your specific application requirements. Ensure compatibility with your system's voltage levels and thermal constraints before ordering.

Selection Notes

Select this component when a single-channel isolator with high EMC immunity is required for automotive designs. Consider the SOIC-8 footprint for space-constrained PCB layouts. Evaluate the 100 Mb/s speed against your bus requirements and ensure the 3000 Vrms isolation meets your safety standards.

Part Context

This part belongs to the ISO7710-Q1 series of reinforced digital isolators. It shares architectural similarities with other members like the ISO7710QDWRQ1 but differs in package type and isolation voltage ratings. The series is characterized by low power consumption and high reliability for automotive use cases.

Replacement Considerations

Direct substitutes may include other ISO7710-Q1 variants such as ISO7710QDWRQ1, though package and isolation voltage differences must be verified. Cross-reference pinouts and electrical specifications carefully to ensure functional equivalence without redesigning the isolation barrier.
