ISO6520FQDRQ1

Overview

The ISO6520FQDRQ1 is an automotive-grade, dual-channel digital isolator from Texas Instruments, designed for functional isolation in harsh environments. It operates with a data rate of 50 Mbps and supports unidirectional signal transmission. The device features galvanic isolation with a rated insulation voltage of 450 Vrms and withstands up to 100 kV/µs common-mode transient immunity. It functions within a supply voltage range of 1.71 V to 5.5 V and operates across a temperature range of -40°C to +125°C. Packaged in an SOIC-8 surface-mount case, it includes a shutdown feature and supports GPIO, PWM, and UART protocols.

Feature Summary

• AEC-Q100 qualified for automotive applications ensuring reliability under extreme conditions
• Provides robust galvanic isolation with high common-mode transient immunity
• Integrates a shutdown pin for power management and system control

Applications

• Automotive engine control units (ECUs)
• Inverter gate drive circuits
• On-board charging systems

Procurement Notes

Verify the specific suffix 'QDRQ1' to confirm automotive qualification and package type. Ensure compatibility with the required logic levels and isolation voltage ratings for the target application. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or handling instructions.

Selection Notes

Select this component when automotive certification and functional safety are required. It is suitable for designs needing dual-channel isolation with low propagation delay. Consider the SOIC-8 footprint constraints and the need for a shutdown capability. Verify that the 50 Mbps speed meets the communication requirements of the connected peripherals.

Part Context

This part belongs to the ISO652x-Q1 family of general-purpose dual-channel automotive functional isolators. It shares architectural similarities with other members but is distinguished by its specific qualification status and packaging. The series focuses on providing reliable signal transmission across isolation barriers in electric and hybrid vehicle architectures.

Replacement Considerations

Direct replacements include other AEC-Q100 qualified dual-channel isolators from Texas Instruments such as the ISO6520DRQ1, provided the automotive grade and shutdown feature are required. Non-automotive equivalents like the ISO6520FDR lack the necessary qualification for automotive use.
