| 摘要： | Cost saving,reliability and fault tolerance requirements are since several years the driving forces for using smart power devices in automotive.Smart Power solid state switches are widely used for power actuator purposes where fault tolerance against system failures in short circuit and overload is essential.The process to design a fault tolerant and reliable power management with real failure condition engages a 2 sides approach:1.The silicon supplier to define optimized short circuit protection for a maximum number of activations and to supply unambiguous speciation of the short circuit ruggedness.2.The system supplier to assess the reliability of the device in short circuit as a function of the fault handling strategy required by the car maker.This paper is a complement to the standard AEC-Q100-012 short circuit specification.The paper describes short circuit protection philosophy,what are the stresses applied to the device and the failure mechanisms.This allows calculating the damage applied to the physical structure at given working and boundary conditions. |
