SFFS780 February 2024 TUSB4020BI-Q1
1 Overview
This document contains information for the TUSB4020BI-Q1 (HTQFP 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.
