Part Review and Datasheet Verification

Make the functional group more general.
Add a Section property to all pins, and apply the same value used in the Pin Group property to each pin's Section property.

Thought for 9 sec

I’ll simplify the pin groups to broader functional categories and mirror each value into the Section property for the same pin.

Worked for 1 min

flux

Updated all pins to broader functional groups and added Section to every pin with the same value as Pin Group.

Open items:

Pins 41–44 are still marked Extra because they are not present in the TI datasheet.
Some Section values like USB, I2C, Ground, and Extra were accepted but are outside Flux’s suggested autocomplete list.

Suggested next steps:

Remove or correct the four extra pins/pads.
Update Pin Type and Pin Description for each pin from the datasheet.

Fix pins and metadata

Remove extra pins

Footprint review

The PCB footprint currently contains pads corresponding to all 44 schematic terminals, including extra pads 41-44. The datasheet package for TPS25750DRJKR is RJK0038B WQFN with 38 perimeter terminals plus two exposed pads, numbered 39 and 40. Therefore the footprint pad count/numbering does not match the datasheet.

Detailed geometry could not be fully verified from the current layout inspection because pad coordinate/size/rule details were not exposed in the returned layout tree. However, the footprint should be checked against TI RJK0038B dimensions:

Body: 5.9-6.1 mm x 3.9-4.1 mm.
Pitch: 0.4 mm.
Terminal width: 0.15-0.25 mm.
Terminal length: 0.3-0.5 mm for 34 perimeter terminals.
Exposed pads: two thermal pads, numbered 39 and 40, requiring solder connection to PCB.

Pin descriptions / types review

Current terminal properties show Pin Type as Unspecified for all terminals and no useful pin descriptions. This is incomplete versus the datasheet. Recommended symbol metadata updates:

LDO_3V3, LDO_1V5, VBUS: Output / Power Out.
VIN_3V3, PP5V: Power In.
PPHV, VBUS_IN: Power / bidirectional high-current path.
GND pins and exposed pad 39: Ground.
DRAIN pins and exposed pad 40: Passive or Power path / internal FET drain.
CC1, CC2, GPIO4/USB_P, GPIO5/USB_N, I2C SDA pins: Bi-Directional.
ADCIN1, ADCIN2, I2Cs_SCL, I2Cm_IRQ: Input.
GPIO2, GPIO3, GPIO6, GPIO7, GPIO11, I2Cs_IRQ, I2Cm_SCL: Output according to datasheet table, noting many GPIOs are configurable in use.

Flagged mismatches and recommended fixes

Critical: Pad/terminal count mismatch. Project has 44 terminals/pads, but TPS25750DRJKR should have 38 package pins plus exposed pads 39 and 40 only. Remove or correct extra pins/pads 41-44: PPHV_4, VBUS_IN_4, VBUS_3, PP5V_3.
Critical: Footprint likely does not match RJK0038B because it includes extra pads 41-44. Rebuild or edit footprint to TI RJK0038B, preserving exposed pads 39 and 40.
Moderate: Project description says 38-WQFN but project pad count is 44. Align metadata after footprint correction.
Moderate: Datasheet URL is set to an uploaded PDF rather than the official TI URL. Since a URL existed, it was not overwritten, but consider changing it to https://www.ti.com/lit/ds/symlink/tps25750.pdf for traceability.
Moderate: Symbol pin types and pin descriptions are incomplete; all inspected terminal Pin Type values are Unspecified.
Minor: I2C pin names use I2CS/I2CM capitalization while datasheet uses I2Cs/I2Cm. This is not electrically significant, but consistency with the datasheet would improve searchability.
