1 Overview

This document contains information for the UCC33011(Q1), UCC33021(Q1), UCC33411(Q1), and UCC33421(Q1) (SSOP-16 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 distribution (FMD) based on the primary function of the device
  • Pin failure mode analysis (pin FMA)

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