1 Overview

This document contains information for LMR51425-Q1 and LMR51435-Q1 (WSON 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 shows the device functional block diagram for reference.
