ISOW1432: Query Regarding Isolated RS485 IC with Integrated DC-DC Output on UART Side

pooja ak

Part Number: ISOW1432

Dear TI Team ,

I am looking for an isolated RS485 transceiver with integrated isolated DC-DC power similar to ISOW1432, but with a different power architecture requirement.

My requirement is to have the isolated DC-DC output available on the UART/logic side. I am planning to use this isolated power output for external circuitry on the UART side.

For better understanding, I have attached the block diagram illustrating the expected architecture.

Could you please suggest an IC that meets this requirement? Untitled Diagram.drawio (1).png

Hi Pooja,

Thanks for reaching and providing detailed inputs.

Currently, we don't have an integrated power solution which matches your above requirement as it is.

You will have to go with an external isolated supply along with a separate isolated RS485 module for such an architecture - You can refer TI's UCC isolated power modules to achieve this Isolated power modules (integrated transformer) | TI.com
