• Power metering applications with high-voltage sensing requirements

Digital Isolators Procurement Notes

Verify the specific suffix 'BRWZ' to confirm the 16-SOIC package and reel packaging format. Ensure the order matches the required isolation voltage rating of 3750 Vrms rather than the standard 3000 Vrms variant. Confirm that the component meets the necessary automotive or industrial qualification standards if applicable to the end product design.

Digital Isolators Selection Notes

Select this component when four isolated bidirectional channels are required in a compact surface-mount package. It is suitable for designs needing high-speed data transfer up to 150 Mbps with significant isolation voltage requirements. Consider the 1.7 V to 5.5 V supply range for compatibility with low-power logic systems.
