Evaluating document queries.

Analyzing the schematic.

Clarifying schematic details.

I can sketch the current schematic symbol connection that exists in this part project.
I should note one limitation: I was able to read the existing terminals in the project, but I could not reliably extract the datasheet text in this session, so this is a drawing of the current symbol/pin mapping in the project, not a datasheet-verified application circuit. Flux’s own part-sync guidance says pin assignments should be taken from the datasheet and not guessed

If you want, I can next do either of these:
  • make a clean pin-symbol drawing for this part, or
  • help you verify each terminal against the datasheet so the symbol is accurate.
