Part Data Review and Validation
Thought for 2 mins 31 sec
I reviewed the current part project for TPS23753APWR.
- Datasheet URL: already set, and it points to the official TI datasheet URL:
http://www.ti.com/lit/gpn/tps23753a - Because that property was already present, no Datasheet URL update was needed
Table
| Field | Current value | Status |
|---|---|---|
| Manufacturer Part Number | TPS23753APWR | OK |
| Manufacturer Name | Texas Instruments | OK |
| Part Type | Integrated Circuits | OK, but generic |
| Designator Prefix | IC | Acceptable for a part project |
| Datasheet URL | http://www.ti.com/lit/gpn/tps23753a | OK |
| Project description | Power Over Ethernet Controller 1 Channel 802.3at (PoE+), 802.3af (PoE) 14-TSSOP | Good |
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
The schematic contains exactly 14 terminals, with these pin-number mappings:
Footprint audit
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
Table
| 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
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
Table
| Spec | Value |
|---|---|
| Device | PoE interface and isolated converter controller |
| Standards | IEEE 802.3at, backward-compatible language for 802.3af |
| Package | TSSOP (PW) |
| Pin count | 14 |
| Temperature range | -40 to 125 C |
| Frequency feature | Programmable frequency with synchronization |
- 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.
