Part Information Audit and Review

flux

Fixed the BQ24074RGTT terminal metadata from the TI datasheet.
Updated all 17 terminals with datasheet-derived Pin Type and Pin Description, including standard pin types for IN, OUT, BAT, VSS, EP, open-drain status outputs, and programming/control pins. Verification passed, and the terminal-related part review checks returned no reported issues.

Please also convert the symbol to parametric style,and place each pin into the correct section based on the datasheet.

flux

I’ll switch the symbol metadata to parametric style, assign each terminal to datasheet-based functional sections, and verify the resulting symbol properties.

flux

Updated the symbol metadata to Parametric style.
I assigned each pin to a datasheet-based section and orientation: power-path pins to Power, VSS/EP to Ground, TS to Analog, and control/programming/status pins to Control. I also set terminal order by datasheet pin number and verified the updates; terminal/parametric review checks returned no reported issues.
