Original question:
Hi,
It is written in the schematics that Disconnect the anode of D25 from the ground and connect it to the anode of D18.
But the thing is that in the CAD file the connection of A-D18 is not there.
So which one I have to follow, the actual available connection in PCB cad file or the one you have mentioned as a note?
What is the importance of this A-D18 connection in a precharge circuit?
Hello Nidheesh
Thanks for the information. I had a look at the document and the reason for this note is that the schematic changed between Rev C and Rev D but the changes were small enough to allow the engineer to build the Rev D schematic on the Rev C boards that he had in stock. You can compare the changes to D25 below.
You can see similar notes on sheet 2 and sheet 1.
We do have the PCB files at Rev C but I think that we never made a Rev D version of the layout.
Regards
Colin
