LM5177 Part Audit


Check this schematic component against the datasheet for [MPN] and assign the correct pin orientation, section, and terminal order without changing, replacing, renumbering, or remapping any pins. Remove the Pin Group property from all pins if it exists. Place Power pins first and Ground pins last. Within each section, distribute the pins as evenly as possible between the left and right sides; for example, split 10 pins as 5/5 and 11 pins as 5/6 or 6/5. If a section contains only one pin, leave it on the most appropriate side. Keep the symbol compact, balanced, and visually symmetrical. If a pin function is unclear, assign Unclear / Check datasheet, then apply all changes directly to the schematic component.
I’ll map all 39 terminals to datasheet-backed functional sections, assign balanced left/right orientations and terminal order, remove Pin Group everywhere, then verify the resulting symbol metadata.
The TI pin table is available; I’m now deriving a compact functional-section layout without altering any pin identity or mapping.
Updated all 39 LM5177DCPR terminals:
  • Assigned seven datasheet-based sections, with Power and Bias first and Ground last.
  • Balanced each section across left/right sides.
  • Assigned unique terminal order values 1–39.
  • Removed Pin Group from every terminal.
  • Preserved all pin names, numbers, mappings, and footprint associations unchanged.
The post-write metadata verification passed.
