Power Over Ethernet Controller 1 Channel 802.3at (PoE+), 802.3af (PoE) 14-TSSOP
Good
Official package / ordering info cross-check
From TI’s official part-details page for TPS23753APWR:
Package: TSSOP (PW)
Pin count: 14
Operating temperature: -40 to 125 C
Function: IEEE 802.3 PoE interface and isolated converter controller
PoE support: 802.3at, with backward compatibility language covering 802.3af
Switching frequency: TI confirms programmable frequency with synchronization, but I could not extract a numeric default/maximum from the available page content
Symbol and terminal audit
The schematic contains exactly 14 terminals, with these pin-number mappings:
The layout footprint asset is SOP65P640X120-14N.kicad_mod and contains 14 SMD pads numbered 1 through 14.
That is consistent with the official TI ordering info for a 14-pin TSSOP/PW package.
Mismatches and gaps found
Confirmed issues
Area
Finding
Severity
Pin typing
All 14 terminals are currently Pin Type = Unspecified
Warning
Parametric symbol metadata
All 14 terminals are missing Section, Pin Group, and Pin Orientation
Warning
Package metadata property
No explicit Package or Case Code project property found
Minor
Electrical metadata
No explicit Operating Temperature property found, even though TI lists -40 to 125 C
Minor
Pin descriptions
No per-pin Pin Description metadata found on terminals
Warning
The review tool also flagged every terminal for missing symbol metadata. For part-project verification, the key requirement is to match the datasheet’s pin count and pin numbering exactly, and to fully populate terminal metadata rather than leaving it unspecified .
What appears correct
MPN matches
Manufacturer matches
Official datasheet URL is already set
Terminal count is 14
Footprint pad count is 14
Terminal numbering is contiguous 1-14
No obvious extra or missing pins from the project side
Important limitation
I could not extract the actual pin-function table text from the TI datasheet content with the available document access path, so I could not definitively verify each pin’s datasheet wording or confirm exact per-pin descriptions from the source PDF.
So the result is:
Pin count and package cross-check: passes
Symbol terminal names/numbers vs expected 14-pin device: looks consistent
Exact pin-description vs datasheet text: not fully verifiable from the retrieved datasheet content
Terminal metadata completeness: fails

Bottom line
No Datasheet URL update was required
Package and pin count look correct
Biggest mismatch is metadata completeness, not the footprint:
all terminal pin types are unspecified
pin descriptions are missing
section / pin group / pin orientation are missing
package/electrical properties are incomplete
If you want, I can turn this into a precise fix list for the 14 terminals, including recommended Pin Type, Section, Pin Group, and short Pin Description values for each pin once we have the pin-function table extracted exactly from the datasheet.
