Done — I added the official TI datasheet URL to the part metadata and created the full audit in BQ25792RQMR Part Audit.
Key findings: the footprint pad count appears plausible because the TI RQM package land pattern uses 33 lands, but the datasheet logical pin table has 29 pins; terminals 30–33 should be documented as duplicated lands, not independent datasheet pins. The main mismatches are missing pin descriptions, all terminal pin types being unspecified, and ~QON potentially being a confusing name versus the datasheet’s QON.

Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, VBUS, GND etc Also can you place them into their respective sections based on their functions NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

I’ll group each existing terminal exactly once by its primary datasheet function, then set both the functional group and section properties on the symbol terminals and verify the result.

2/2 tasks completed.

Thought for a moment

Done — I assigned every existing terminal to exactly one datasheet-based functional group and a broad section, then verified the updates.
Examples: VBUS pins are grouped as Power Input, GND as Ground, SCL/SDA as I2C Interface, D+/D− as USB Data Detection, BAT/BATP as battery-related groups, and SW/BTST pins under switching/driver groups. Duplicate package lands like STAT_2, VAC1_2, TS_2, and SDRV_2 were kept in their matching primary function group and described as duplicate lands, not separate logical pins.
