Part Review and Datasheet Verification
Worked for 3 mins 3 sec
Reviewed the BQ34210IPWRQ1 part against the TI bq34210-Q1 datasheet and created the report: Part Review: BQ34210IPWRQ1.
No pinout or footprint mismatch was found; the TSSOP-14 / PW footprint matches the datasheet land pattern closely. Main cleanup items: blank Part Type, all pin types are
Unspecified, missing pin descriptions, and the Datasheet URL is an uploaded TI PDF rather than the TI web URL.
Fix the metadata issues, update pin types and descriptions, then run ERC/DRC.
Thought for 6 sec
I’ll update the part metadata and terminal pin properties from the datasheet, then run schematic/layout checks and report any remaining issues.
Worked for 2 mins 29 sec
Updated the BQ34210IPWRQ1 metadata and terminal properties from the TI datasheet: Part Type is set, package/datasheet metadata is present, and all 14 pins now have electrical pin types, descriptions, groups, and sections.
ERC/DRC review completed with no open ERROR, WARNING, UNCERTAIN, or OPEN checks reported.
Suggested next steps:
- Publish/update the part library record if this is ready for reuse.
- Optionally standardize NC pin grouping if you prefer a different internal convention.
- Run a final visual symbol/footprint review before release.

The part already had a Datasheet URL set, so I did not overwrite it. The current URL points to an uploaded copy of the TI datasheet; the Flux library record also contains a TI redirect URL for the same bq34210-Q1 datasheet.
Datasheet source checked
Texas Instruments bq34210-Q1 datasheet, SLUSCG1, “Automotive 1-Series Cell System-Side CEDV Fuel Gauge for Rarely Discharged Batteries.”
Key datasheet specs
- Function: Automotive 1-series system-side CEDV fuel gauge for rarely discharged backup batteries.

Symbol review
- The symbol has 14 terminals and the pin-number-to-name mapping matches the datasheet.
- The left/right grouping is logical: I2C/power input pins on the left, alert/sense/TS pins on the right.
- NC pins are uniquely represented as NC_1 through NC_5 and mapped to datasheet pins 4, 6, 8, 11, and 13.
Footprint review
- The footprint has 14 pads, consistent with TSSOP-14 / PW0014A.
- Pad pitch is 0.65 mm, consistent with the datasheet.
- Pad nominal size is approximately 1.475 mm × 0.45 mm, matching the datasheet recommended 1.5 mm × 0.45 mm land pattern closely.
- Row span is approximately 5.876 mm pad-center-to-pad-center, consistent with the datasheet 5.8 mm land-pattern guidance.
- No thermal pad is expected for this PW0014A TSSOP package, and none was found.
Mismatches / cleanup items
- Part Type property is blank. Recommend setting it to Integrated Circuit or a more specific fuel-gauge / battery-management category if available.
- Pin Type properties are all
Unspecified. Datasheet types should be encoded for better ERC and documentation:- SDA, SCL, ALERT: Bi-Directional or Open Collector / open-drain-equivalent where supported.
- VSS: Ground.
- REGIN: Power In.
- REG18: Power Out or Power, with description clarifying capacitor-only LDO node.
- SRP, SRN, TS: Input / analog input.
- NC pins: Not Connected.
- Pin descriptions are missing from the symbol terminals. Recommend adding concise datasheet-based descriptions for all pins.
- Datasheet URL is not the TI web URL in the project metadata. It points to an uploaded PDF copy. This is usable and appears to be the correct TI datasheet, but if you want the part to reference the official TI URL directly, use the TI URL from the library record.
- Package property is not explicitly visible in part properties. The footprint itself matches TSSOP-14 PW0014A, but adding a package property such as
TSSOP-14 (PW)would improve searchability and review clarity.
Overall result
No functional pinout or footprint mismatch was found. The main issues are metadata quality: blank Part Type, unspecified pin electrical types, missing pin descriptions, and optional replacement of the uploaded datasheet URL with the official TI URL.
