Datasheet 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 use the L9780 datasheet to classify all 48 pins, remove Pin Group, assign sections and terminal order, and rebalance the symbol while preserving every existing pin number and mapping.
Updated the L9780 symbol directly: all 48 pins now have datasheet-based sections, balanced left/right orientation, and unique terminal order. Power pins are first, grounds last, and all Pin Group properties were removed.
Verification confirms pins 1–48 remain present exactly once with no renumbering, remapping, replacement, or name changes. No unclear pin functions remained.
