1 Overview

This document contains information for the TPS55288-Q1 and TPS552882-Q1 (VQFN-HR 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 1-1 and Figure 1-2 show the device functional block diagrams for reference.
