Abstract

We present the design of a cycle test system for automated stress testing of smart power switches under automotive load short circuit conditions up to 250A / 50V. A fast overcurrent detection and shutdown strategy protects the test equipment from damage. Device degradation and failure data are recorded individually for statistical analysis of time-to-failure distributions. Representative measurements show that our system meets the requirements of the AEC standard Q100-012.
