Overview

The ISO7321FCQDRQ1 is an automotive-qualified, dual-channel digital isolator designed to provide up to 3000Vrms isolation. This device features one forward and one reverse channel, making it ideal for bidirectional communication buses that require galvanic isolation to prevent noise currents from entering the local ground.

Why Choose This Part

This isolator is AEC-Q100 qualified for automotive use and features a 25-year isolation barrier life. It offers high common-mode transient immunity (CMTI) of 65-kV/us at 5V supplies and includes an integrated noise filter on the inputs for robust electromagnetic compatibility.

Applications

Automotive CAN Bus
Provides galvanic isolation for CAN transceivers in electric vehicle battery management systems and powertrain applications.
Industrial Fieldbus
Isolates RS-485, RS-232, or SPI interfaces in noisy industrial automation environments to maintain signal integrity.
Ground Loop Elimination
Used in systems with large ground potential differences to prevent circulating currents that can damage sensitive electronics.
Power Supply Feedback
Acts as an isolated feedback path for switched-mode power supplies requiring high transient immunity.

Getting Started

When designing with this part, ensure 0.1uF bypass capacitors are placed as close as possible to the VCC pins on both sides of the isolation barrier. For automotive compliance, follow PCB creepage and clearance requirements as specified by the 8-SOIC package footprint to maintain the 3000Vrms isolation rating.
