Part Review and Datasheet Update


Completed the TPS274160BRLHR part review and saved the detailed findings in TPS274160BRLHR Part Review (tps274160brlhr-part-review). The symbol pin names/numbers match the TPS274160B RLH WQFN-28 datasheet, and the footprint pad count matches 28 pins plus exposed pad.
Open items flagged:
  • Part Type is currently Electromechanical Components; it should be an IC/power switch classification.
  • Pin Type and Pin Description fields are mostly missing/unspecified.
  • Datasheet URL is set, but it points to an uploaded PDF rather than TI’s canonical URL: https://www.ti.com/lit/ds/symlink/tps274160.pdf.
  • Exact pad geometry could not be numerically verified from the available layout output, though pad count/naming are consistent.
Suggested next steps:
  1. Update metadata: Part Type, Package/Case, and canonical Datasheet URL.
  2. Populate terminal Pin Type and Pin Description fields from the datasheet.
  3. Re-check footprint pad geometry against TI RLH0028A land pattern dimensions.
Populate all Pin Type and Pin Description fields from the TPS274160B datasheet.
I’ll update each terminal’s Pin Type and Pin Description from the TPS274160B datasheet, then re-read the schematic to verify the fields are populated.
The first pass populated all fields; I’m normalizing the few Pin Type values to Flux’s standard options before verification.
Populated and verified Pin Type and Pin Description for all 29 terminals from the TPS274160B datasheet.
Open items:
  • Used Flux-standard Pin Type values where needed: Open Collector for the open-drain FAULT pin, Power In for VS pins, Ground for GND pins, and Passive for EP.
Suggested next steps:
  1. Run a final part/library review check.
  2. Verify footprint pad geometry against TI RLH0028A land pattern dimensions.
  3. Publish or update the part once metadata cleanup is complete.
