Part Audit Review

A

adrian95

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

I’ll audit the part metadata, locate the official datasheet if needed, verify the symbol/footprint/pins against it, and document any mismatches or corrections.

I’m reading the current metadata, terminal definitions, rendered symbol, and PCB land pattern now; next I’ll compare them to the manufacturer package drawing and pin table.

Audit complete. The official Analog Devices datasheet URL was already set, and all 14 lead names/numbers plus the exposed pad match; however, the description incorrectly claims self-discharge detection, terminal descriptions/types are missing, and package metadata is incomplete. The exposed-pad paste pattern also remains unverified because ADI land-pattern drawing 90-0063 was unavailable.

Key specifications
  • Function: Stand-alone pack-side 1-cell Li-ion/Li-polymer ModelGauge m5 EZ fuel gauge with 2-level protector.
  • Authentication: SHA-256 with a 160-bit secret key and unique 64-bit ID.
  • Interface: I2C for MAX17301G+; multifunction pins retain family naming such as SDA/DQ and SCL/OD.
  • Recommended operating VBATT: 2.3 V to 4.9 V.
  • Operating temperature: -40 C to +85 C.
  • Typical supply current: 24 uA active, 18 uA hibernate; lower-current ship/deep-ship modes are available.
  • Measurement: 78.125 uV voltage resolution; current-sense input range +/-51.2 mV and 1.5625 uV resolution.
  • Package: 14-lead TDFN-EP, 3.0 mm x 3.0 mm x 0.75 mm nominal, 0.40 mm pitch, package code T1433+2C.
  • Package exposed pad: 1.70 mm x 2.30 mm nominal package metal; connect EP to CSP for normal operation.

Symbol deficiencies
  • Every terminal has Pin Type = Unspecified.
  • Pin Description is missing for every terminal.
  • Pin Group, Section, orientation metadata, and terminal order are not populated as semantic properties.
  • The symbol geometry and left/right grouping are readable, but the absent electrical types reduce ERC usefulness.
  • Suggested electrical classifications include: TH input; CP/REG power outputs; BATT power input; CSP/EP ground; CSN analog input; SDA/DQ bidirectional open-drain; SCL/OD input; ALRT/PIO open-drain/bidirectional multifunction; PFAIL output; PCKP analog input; DIS/CHG outputs; ZVC input.
Footprint cross-check
Confirmed matches
  • 14 perimeter pads plus one exposed pad.
  • 0.40 mm lead pitch.
  • 3 mm x 3 mm body outline.
  • Pin-1 marker and top-view numbering sequence are consistent: pins 1-7 run up the left side and pins 8-14 run down the right side.
  • Perimeter copper pads are 0.20 mm wide x 0.75 mm long, a plausible land pattern for the 0.20 +/-0.05 mm package leads.
  • Exposed copper pad is 1.80 mm x 2.40 mm, 0.10 mm larger in each axis than the nominal 1.70 mm x 2.30 mm package exposed metal, which is a plausible solder land allowance.
Risks / unverified details
  • The exposed pad currently uses one solid 1.80 mm x 2.40 mm paste aperture. Large exposed pads commonly require a segmented/reduced paste pattern to limit float and voiding. The official 90-0063 land-pattern drawing was unavailable at the tested public URL, so the exact Analog Devices paste recommendation could not be confirmed.
  • The footprint file description says T1433+2C, while the package outline drawing uses T1433-2C; the datasheet states suffix symbols indicate RoHS status and the drawing still applies, so this is not a geometry mismatch.
  • Courtyard is 4.25 mm x 3.60 mm. No mismatch was established, but it was not compared against the unavailable official land-pattern drawing.
Mismatches and priority
  1. High — Incorrect description: MAX17301G+ should not claim internal self-discharge detection; that feature is specified for MAX17300/MAX17310 only.
  2. Medium — Missing terminal descriptions/types: Pin names and numbers are correct, but all 15 terminals lack datasheet-backed descriptions and meaningful electrical types, weakening ERC and reuse quality.
  3. Medium — Missing package property: Add Package or Case Code = 14 TDFN-EP, 3 mm x 3 mm, T1433+2C or the closest canonical package value supported by the property system.
  4. Low/medium — EP paste pattern requires confirmation: The solid paste aperture may differ from the manufacturer-recommended stencil pattern; verify against land-pattern drawing 90-0063 or assembly-house guidance before production.
  5. Informational — Pin-count wording: The device is a 14-lead package with an exposed pad, although the Flux footprint correctly contains 15 electrical/copper pad objects.
Overall assessment
The MPN, manufacturer, official datasheet link, package family, footprint pitch, pad numbering, and complete logical pin-name mapping are correct. The part needs metadata cleanup—especially removal of the unsupported self-discharge claim and addition of pin descriptions/electrical types—before it should be considered a high-quality reusable library part. The footprint appears dimensionally plausible, but the EP stencil pattern remains unverified because the referenced official land-pattern document was not publicly accessible at the tested URL.
