The TI functional safety products are hardware components developed as functional Safety Elements out of Context. As such, TI's functional safety activities focus on those related to management of functional safety around hardware component development. System level architecture, design, and functional safety analysis are not within the scope of TI activities and are the responsibility of the customer. Some techniques for integrating the SEooC safety analysis of this hardware component into the system level can be found in ISO 26262-11.
