ST7580 - PLM01 DC Question

[Jonathan Frech]

I'm speaking about the X-Nucle-PLM01A1 Board that uses the ST7580 IC. I would like to use this IC in a DC Bus application, not AC Line, like most of the reference design does. On page 13 of UM2189 is shown how the boards are connected.

My question is, why is the powerline wiring standalone? Why isn't the bus "riding" on top of the 12V VCC?

In my application, i would like to do exactly that. Using 12V for Supply and having Powerline on the same 12V line, so the the device will only need two wires.

Can i just connect PLM Clamp to VCC Clamp? Or is there any other thing needed?

Thanks for your help

Does someone can provide help here?

Did you find an answer meanwhile ?

I would be interested too.

Any update on this @Community member​  @FWall.2​ 

1. I'm interested in the same question on the DC application. I expect no issue here, but a confirmation and design guide would be highly appreciated.
2. I'm interested in DC applications with supply and return lines separated from each other, no parallel conductors or controlled impedance. worst case, return could be through earth. Is it feasible? Limitations on data rate, nodes?
