5.4.3 Functional Safety Constraints and Assumptions

In creating a functional Safety Element out of Context (SEooC) concept and doing the functional safety analysis, TI generates a series of assumptions on system level design, functional safety concept, and requirements. These assumptions (sometimes called Assumptions of Use) are listed below. Additional assumptions about the detailed implementation of safety mechanisms are separately located in Section 5.3.

The TCAN1164-Q1 Functional Safety Analysis was done under the following system assumptions:

  • [SA_1] The system integrator shall not exceed the recommended operating conditions in the component data sheet.
  • [SA_2] A typical application is as shown in Figure 5-3

During integration activities these assumptions of use and integration guidelines described for this component shall be considered. Use caution if one of the above functional safety assumptions on this component cannot be met, as some identified gaps may be unresolvable at the system level.
