4.1 Targeted Applications

The TPS3704x-Q1 component is targeted at general-purpose functional safety applications. This is called Safety Element out of Context (SEooC) development according to ISO 26262-10. In this case, the development is done based on assumptions on the conditions of the semiconductor component usage, and then the assumptions are verified at the system level. This method is also used to meet the related requirements of IEC 61508 at the semiconductor level. This section describes some of the target applications for this component, the component safety concept, and then describes the assumptions about the systems (also known as Assumptions of Use or AoU) that were made in performing the safety analysis.

Example target applications include, but are not limited to, the following:

  • Advanced Driver Assistance System (ADAS)
  • Automotive infotainment & cluster
  • HEV/EV
  • Body electronics and lighting
  • Factory automation
  • Building automoation
  • Medical
  • Motor Drives
  • Grid infrastructure
  • Wireless infrastructure
  • Data center & enterprise computing
