1 Overview

This document contains information for TPS3842 (DRL 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 and Figure 1-2 show the device functional block diagram for reference.
