1 Overview

This document contains information for UCC28C50-Q1, UCC28C51-Q1, UCC28C52-Q1, UCC28C53-Q1, UCC28C54-Q1, UCC28C55-Q1, UCC28C56H-Q1, UCC28C56L-Q1, UCC28C57H-Q1, UCC28C57L-Q1, UCC28C58-Q1, and UCC28C59-Q1, SOIC (8) package, to aid in a functional safety system design. Information provided are:

  • Functional Safety Failure In Time (FIT) rates of the semiconductor component estimated by the application of

    industry reliability standards

  • Component failure modes and their distribution (FMD) based on the primary function of the device
  • Pin failure mode analysis (Pin FMA)

Figure 1-1shows the device functional block diagram for reference.
