Part Audit Review

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 symbol/footprint/pin mapping, update the Datasheet property, and document any mismatches.

The part already has an official ST datasheet URL. I’m now validating every pin and the Flexiwatt25 footprint against that document.

Part Audit Scope
Audit of the published TDA7850 part metadata, schematic symbol, Flexiwatt25 vertical footprint, and pin descriptions against the official STMicroelectronics datasheet.
Authoritative source
  • MPN: TDA7850
  • Manufacturer: STMicroelectronics
  • Official datasheet: https://www.st.com/resource/en/datasheet/tda7850.pdf
  • Datasheet revision reviewed: Rev. 6, September 2013
  • Package variant: Flexiwatt25 (vertical); the horizontal package is associated with TDA7850H.
The Datasheet URL property was already populated with the official ST URL, so no property update was necessary.
Existing part metadata Key specifications
  • Four-channel Class-AB automotive audio power amplifier with four BTL outputs.

flux

Audit complete. The existing Datasheet property already points to the official STMicroelectronics PDF, so no update was required.
Key issues: the description incorrectly says stereo instead of four-channel/quad; four positive BTL outputs omit +; pin 20 is labeled VCC_1; all pin types and descriptions are unspecified; and the footprint’s drill, annular ring, orientation, and STEP alignment need physical validation before manufacturing. Full specifications and findings are in the Part Audit.
