Part Audit Report


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, update its Datasheet property, then compare symbol pins, footprint, and descriptions against the manufacturer documentation.

Part Audit Report Scope
Audit of MFS2633AMDA0AD metadata, schematic symbol, PCB footprint, and pin descriptions against NXP's official FS26 short data sheet, FS26_SDS Rev. 6.1 (30 July 2026).
Metadata review Key specifications
  • Automotive power system basis chip developed for ISO 26262 systems up to ASIL D.
  • MFS2633...D variant: 1.65 A VCORE class, two tracking regulators, FS1B, long-duration timer, ASIL D feature set, blank OTP engineering-development variant.
  • 40 V DC maximum input capability.
  • Operation down to 3.2 V battery with VBST used at the front end; down to 6 V without front-end VBST.
  • VPRE synchronous buck: up to 1.5 A.
Audit complete. The datasheet was already populated, so no property update was needed; all 49 pin numbers map correctly, but two labels are wrong (WAKE_2, VMONTEXT), all pin types/descriptions are missing, the Logic/AND classification is incorrect, and the exposed-pad/paste geometry needs verification.
