1 Overview

This document contains information for DRV8889-Q1 and DRV8889A-Q1 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)

DRV8889-Q1 and DRV8889A-Q1 were developed using a quality-managed development process, but were not developed in accordance with the IEC 61508 or ISO 26262 standards.

Figure 1-1 shows the functional block diagram for the DRV8889-Q1 and DRV8889A-Q1 as a reference.
