1 Overview

This document contains information for TCAN1044A-Q1, TCAN1044AV-Q1, and TCAN1044AEV-Q1. These are Controller Area Network (CAN) transceivers. The TCAN1044A-Q1 and TCAN1044AV-Q1 come in the SOIC (D), VSON (DRB), and SOT (DDF) packages to aid in a functional safety system design. The TCAN1044AEV-Q1 comes in the SOIC (D) and SOT (DDF) packages to aid in 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 TCAN1044A-Q1, TCAN1044AV-Q1, and TCAN1044AEV-Q1

#GUID-E488EBD4-511E-41B0-B770-91A9719CA4DD shows the device functional block diagram for reference. TCAN1044AV-Q1 and TCAN1044AEV-Q1 have the V_IO input at pin 5, while TCAN1044A-Q1 has a no connect (NC) at pin 5.

TCAN1044A-Q1, TCAN1044AV-Q1, and TCAN1044AEV-Q1 were developed using a quality-managed development process, but were not developed in accordance with the IEC 61508 or ISO 26262 standards.
