ISO6720QDWVRQ1

Overview

The ISO6720QDWVRQ1 is an automotive-grade, general-purpose dual-channel digital isolator manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide galvanic isolation with a rated insulation voltage of 5000 Vrms. The device supports data rates up to 50 Mb/s and operates within a supply voltage range of 1.71 V to 5.5 V. Key electrical specifications include a propagation delay of 11 ns, rise and fall times of 5.3 ns maximum, and a pulse width distortion of 20 ns. It functions reliably across an operating temperature range from -40°C to +125°C and is housed in an SOIC-8 package.

Feature Summary

• Automotive qualification compliant for robust performance in vehicle environments
• Capacitive coupling architecture ensures high-speed signal integrity with low power consumption
• Reinforced insulation rating provides enhanced safety margins for critical applications

Applications

• Automotive gateway systems requiring isolated communication channels
• On-board charger (OBC) control circuits
• Battery management system (BMS) interfaces
• Inverter and motor drive control logic isolation

Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the 'DWR' package code matches the required SOIC-8 surface mount footprint. Confirm that the manufacturer's datasheet explicitly lists this part number as active and available for production use before finalizing design-in decisions.

Selection Notes

Select this component when dual-channel isolation at 50 Mbps is required for automotive applications. It is suitable for designs needing reinforced insulation ratings and operation over extended industrial temperature ranges. Consider the unidirectional channel configuration and lack of shutdown pins when evaluating interface requirements against alternative isolators.

Part Context

This device belongs to the ISO6720-Q1 family of digital isolators designed specifically for automotive electronics. It complements other Texas Instruments isolation products by offering a balance of speed, power efficiency, and safety certification documentation. The series supports functional safety system design through available documentation aids.

FAQ
