Audit reconciled and verified. The part has a critical defect: TI specifies a 10-pin RPW VQFN-HR, but the Flux part exposes 14 independent terminals/pads; pins 11–14 are invalid auxiliary copper sections. Symbol aliases are also variant-inaccurate, and all pin types/descriptions are missing. An internal part-quality issue was filed.
The Datasheet URL was already populated, so it was not changed. Key specs and the complete metadata, symbol, footprint, and pin-by-pin comparison are in Part Audit. Do not use or publish this part until corrected.
Metadata/property audit — Completed. All populated project properties, library-index properties, terminal properties, symbol data, footprint geometry, and attached/embedded assets were inspected.
Datasheet cross-check — Completed. The part was checked against the Texas Instruments TPS25947 family datasheet and TI part-detail data for TPS259470ARPWR.
Datasheet property update — Unattempted by design. The property was not absent, so no mutation was allowed by the task scope.
Symbol/footprint correction — Unattempted by design. Geometry and terminals were audit-only.
Overall verdict
Serious unusable part defect: the exact orderable device is a 10-pin RPW VQFN-HR, but this part exposes 14 independent schematic terminals and 14 independently numbered PCB pads. Four copper rectangles that appear to be auxiliary portions of corner lands were incorrectly promoted to pins 11–14. The symbol also uses family-wide alias names rather than the exact TPS259470A functions, all pin electrical types are unspecified, and all pin descriptions are absent. The part should not be used until its terminals and pad bindings are corrected and republished.
Datasheet URL status
Canonical official TI PDF: https://www.ti.com/lit/ds/symlink/tps25947.pdf
The published library index currently reports an official ti.com datasheet URL for this Part UID.
The current editable project metadata reports a populated Flux-hosted uploaded PDF URL instead of the canonical TI URL.
No edit was made because the instruction permitted setting Datasheet URL only when missing. This creates a publication/editor-index uncertainty that should be reconciled during repair.
The datasheet reader identified the attached document as the official TI datasheet, revision SLVSFC9C, May 2026, but did not return immutable inline citation URIs in this run; the factual values below were therefore manually cross-checked against the official TI PDF.

Published-library index divergence
The indexed published record for the same Part UID still reports stale values including Mount = Reverse, Package or Case Code = TO, blank Part Type, an older garbled description (28-m?), and 14 terminals. It also reports an official TI datasheet URL. The current editor project has corrected several metadata fields, but the terminal defect remains. This suggests the editor state and published search index are not fully synchronized or the fixes have not been republished.
Exact TI device and key electrical specifications
TPS259470ARPWR is the tape-and-reel orderable form of the TPS259470A in the TPS25947xx eFuse family. The TPS259470A option provides:
Adjustable overvoltage lockout (OVLO)
Active current limiting
AUXOFF output on pin 3
Active-low FLT output on pin 4
Auto-retry fault response
2.7 V to 23 V recommended input range; 28 V absolute maximum
Up to 5.5 A continuous switch current at TJ ≤ 125 °C
Adjustable current-limit range of 0.5 A to 6 A
Approximately 28.2–28.3 mΩ typical on-resistance at the stated datasheet conditions; 45 mΩ maximum across operating range
Input reverse-polarity withstand down to –15 V subject to the datasheet limits
–40 °C to +125 °C operating junction range
Package and footprint comparison
TI package
Package code: RPW
Package drawing: RPW0010A
Package name: VQFN-HR / HotRod QFN
Electrical pin count: 10
Nominal body: 2.0 mm × 2.0 mm; drawing limits 1.9 mm to 2.1 mm
Maximum package height: 1.0 mm
No separate exposed thermal-pad terminal is specified. The enlarged IN and OUT power lands provide electrical and thermal conduction.
Lead spacing is non-uniform around the sides: the footprint uses 0.475 mm, 0.45 mm, and 0.475 mm center-to-center intervals, matching the RPW land-pattern dimensions rather than a single uniform pitch.
Current footprint
Embedded module name: TPS25970ARPWR — typo: missing the digit 4.
Fabrication body outline: 2.0 mm × 2.0 mm — correct nominal body.
Courtyard: 4.4 mm × 4.4 mm.
Pad geometry:
Pads 1, 4, 7, 10: 0.30 mm × 0.60 mm
Pads 2, 3, 8, 9: 0.25 mm × 0.60 mm
Pads 5 and 6: 0.30 mm × 2.40 mm enlarged IN/OUT lands
Pads 11–14: 0.25 mm × 0.35 mm corner/edge rectangles
Physical placement and copper dimensions closely resemble the TI land-pattern example.
Pin-1 indication exists as a very small silkscreen arc/dot near the pin-1 corner; pin 1 also uses a wider end pad than adjacent inner pins.
A STEP model TPS259470ARPWR.stp is embedded.
Footprint defect
The copper geometry appears broadly correct, but the electrical numbering is not. The four extra corner/edge rectangles should not create pins 11–14. Based on their adjacency, they appear intended to be repeated copper portions of corner terminals:
Current pad 11 adjacent to pin 1 land → should be bound to electrical pin 1
Current pad 12 adjacent to pin 4 land → should be bound to electrical pin 4
Current pad 13 adjacent to pin 7 land → should be bound to electrical pin 7
Current pad 14 adjacent to pin 10 land → should be bound to electrical pin 10
This repeated-pad binding must be verified against TI CAD/package data during repair, but the datasheet is unequivocal that the package has only pins 1–10.
Symbol and terminal audit
All 14 current terminals have Pin Type = Unspecified, no terminal descriptions, no sections/groups/orders, and only pin number plus symbol position populated.

Mismatches and uncertainties
Critical
Four nonexistent electrical terminals/pads (11–14). This changes net connectivity and makes the part unsafe to use.
Wrong pad-to-terminal bindings for the auxiliary corner copper. Physical geometry may solder correctly, but electrical net assignment will not.
Exact-variant symbol is polluted with other family variants' functions (OVCSEL, PG, PGTH).
Major quality defects
All electrical pin types are unspecified.
All pin descriptions are missing.
The footprint source/module filename is misspelled as TPS25970ARPWR.
Current editor Datasheet URL is not TI-domain, while the published index has the official URL.
Published search metadata is stale/incorrect (TO, Reverse, blank Part Type) relative to the editor project.
Minor/uncertain
The pin-1 silkscreen marker exists but is extremely small and may be difficult to manufacture/read.
The 4.4 mm square courtyard is much larger than the 2 mm body; this is conservative rather than electrically wrong, but should be reviewed against the intended courtyard standard.
The inferred repeated-pad mapping 11→1, 12→4, 13→7, 14→10 is strongly supported by geometry, but should be confirmed with TI's official CAD data before editing.
Escalation recommendation
Escalate this library part as a part quality issue. Repair should reduce the part to 10 schematic terminals, use exact TPS259470A names/functions, assign electrical types and descriptions, and bind the four auxiliary copper rectangles to the appropriate existing corner pin numbers instead of independent terminals. Republish after confirming the editor metadata and published search index agree.
