This document contains information for TCAN1043-Q1 (as well as the TCAN1043G-Q1, TCAN1043H-Q1, and TCAN1043HG-Q1), a controller area network (CAN) transceiver, to aid in a functional safety system design. The TCAN1043-Q1 comes in the SOIC (D) and VSON (DMT) 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 (Pin FMA)

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

TCAN1043-Q1 was developed using a quality-managed development process, but was not developed in accordance with the IEC 61508 or ISO 26262 standards.
