1 Overview

This document contains information for TCAN1462-Q1 and TCAN1462V-Q1 to aid in a functional safety system design. These devices are Controller Area Network (CAN) Signal improvement capable (SIC) transceivers compliant to CiA 601-4 and are available in the SOIC (D), VSON (DRB), and SOT (DDF) packages. 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 TCAN1462-Q1 and TCAN1462V-Q1

Figure 1-1 shows the device functional block diagram for reference. TCAN1462V-Q1 has the V_IO input at pin 5, while TCAN1462-Q1 has a no connect (NC) at pin 5.

TCAN1462-Q1 and TCAN1462V-Q1 were developed using a quality-managed development process, but were not developed in accordance with the IEC 61508 or ISO 26262 standards.
