How to isolate signal and power in isolated CAN systems

In this paper from Texas Instruments, Neel Seshan, Product Marketing Engineer, Isolation, Interface Group explains how to Isolate Signal and Power in Isolated CAN Systems; with the increase in the usage of signal isolation in many industrial and automotive applications, the need for isolated power has also increased.

The benefits of isolation are lost if the power supplies on either side of the isolation barrier are simply shorted. If the isolated power sub-systems are not designed carefully, it affects the overall system performance like temperature rise due to poor power transfer efficiency, data corruption due to emissions, and so on.

To simplify the design process of isolated CAN sub-systems, this document provides various options (discrete and integrated) to isolate CAN signals and power.
