ISO7760FQDWRQ1

Overview

The ISO7760FQDWRQ1 is an automotive-grade, six-channel digital isolator from the ISO776x-Q1 family, manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide robust signal isolation with a 5000 Vrms insulation voltage rating per UL 1577. The device supports data rates up to 100 Mbps and features a common-mode transient immunity of 85 kV/µs. Operating on a supply voltage range of 2.25 V to 5.5 V, it offers unidirectional channel configuration (6/0) in a 16-SOIC package. Certified under AEC-Q100 standards, it ensures reliability for harsh automotive environments across a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-performance isolation for six independent channels using capacitive coupling technology.
• Delivers robust electromagnetic compatibility (EMC) performance suitable for demanding automotive applications.
• Ensures signal integrity with high common-mode transient immunity and low propagation delay.
• Complies with AEC-Q100 qualification standards for automotive electronic components.

Applications

• Automotive gateway systems requiring multi-channel signal isolation
• In-vehicle network interfaces such as CAN and LIN bus isolation
• Battery management systems (BMS) for isolated communication channels
• Advanced driver-assistance systems (ADAS) sensor interface isolation

Procurement Notes

Verify the specific suffix 'F' indicates the correct insulation rating and package variant for your design requirements. Confirm that the 16-SOIC footprint matches your PCB layout constraints. Ensure the component meets the required AEC-Q100 grade for your specific automotive application tier. Cross-reference the datasheet for thermal dissipation limits within your enclosure design.

Selection Notes

Select this component when six isolated channels are required in a single package to save board space. Choose the SOIC-16 package if wider spacing between isolation barriers is preferred over SSOP options. Consider the 5000 Vrms rating for applications requiring higher dielectric strength compared to 3000 Vrms variants. Evaluate the 100 Mbps data rate against system timing requirements to ensure adequate bandwidth.

Part Context

This part belongs to the ISO776x-Q1 series of automotive digital isolators. It shares functional similarities with other members like the ISO7760QDWRQ1 but differs in specific insulation ratings or package types depending on the suffix. The series is designed to replace magnetic isolators in automotive networks, offering smaller size and lower power consumption while maintaining high reliability.

Replacement Considerations

The ISO7760QDWRQ1 serves as a direct pin-compatible alternative within the same family. Verify that the insulation voltage and package dimensions match your existing design constraints before substitution. Check for any differences in propagation delay or power consumption specifications between the two variants.
