AN2689 Protection of automotive electronics from electrical hazards, guidelines for design and component selection

Application Note from STMicroelectronics, 2008. — 41 p.The objective of this document is to help electronic module designers with a protection design approach for selecting the most suitable devices for typical applications depending on the protection standard the electronic module has to meet. Section 1 describes the electrical hazards considered in this document. Section 2 presents a list of parameters to be taken into account before selecting possible protection devices. Section 3 and Section 4 provide worked design examples, with design calculations, for several protection solutions. Section 5 provides recommendations for the design of PCB layout for improved solutions.
