Updated the Datasheet URL to the official TI PDF, added datasheet-derived pin types/descriptions/groups/sections, and corrected the footprint pads to TI’s RUK0020B land pattern: 0.20 × 0.60 mm perimeter pads and 1.70 × 1.70 mm exposed pad.
Open items:
ERC/DRC returned no errors or warnings at the latest review timestamp.
The project description still appears to describe a different USB charging/ESD part; it should be corrected separately if desired.
Suggested next steps:
Ask me to clean up the project description.
Ask me to rerun component review checks after any manual edits.
Ask me to rename ~FLT to exact datasheet text FLT if you prefer strict datasheet pin naming.
