1 Overview

This document contains information for TCAN1043A-Q1. This is a Controller Area Network (CAN) transceiver in the SOIC (D), VSON (DMT), and SOT (DYY) packages 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 (FMA) for the device pins of TCAN1043A-Q1

Figure 1-1 shows the device functional block diagram for reference.

TCAN1043A-Q1 was developed using a quality-managed development process, but was not developed in accordance with the IEC 61508 or ISO 26262 standards.
