ISO7761FQDWRQ1

Overview

The ISO7761FQDWRQ1 is a six-channel reinforced digital isolator from Texas Instruments, designed for automotive applications with robust electromagnetic compatibility. It features capacitive coupling technology and operates within a supply voltage range of 2.25 V to 5.5 V. The device provides a data rate of 100 Mb/s and an insulation voltage of 5000 Vrms. It is housed in a SOIC-16 package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Six-channel configuration with unidirectional signal transmission
• Reinforced isolation capabilities for safety-critical systems
• High-speed data transfer at 100 Mb/s
• Automotive-grade reliability with robust EMC performance

Applications

• Automotive electronic control units (ECUs)
• Inverter gate drive circuits
• Motor control systems
• Battery management systems

Procurement Notes

Verify the specific suffix 'DW' indicates the SOIC-16 wide package variant. Confirm the 'Q1' designation ensures compliance with AEC-Q100 automotive standards. Check datasheet revisions for any updates on recommended operating conditions or thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when high channel density and reinforced isolation are required in space-constrained automotive designs. Ensure the 100 Mb/s data rate meets system timing requirements. Compare power consumption against lower-speed alternatives if energy efficiency is a primary constraint. Validate that the SOIC-16 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ISO77x-Q1 family of automotive digital isolators. It offers higher channel count compared to dual or quad-channel variants like the ISO7721 or ISO7741. It shares similar interface characteristics with other members but distinguishes itself through its six-channel architecture and reinforced isolation rating suitable for stringent automotive safety standards.

Replacement Considerations

ISO7761FQDBQRQ1: Offers similar functionality but in a DBQ package with different isolation ratings. ISO7761QDWRQ1: Standard version without the 'F' suffix, potentially differing in EMC performance or specific automotive qualification details.
