Smart power switches are widely used as short-circuit protection devices in automotive systems. Therefore the robustness of the device under repetitive short-circuit stress is crucial for the entire system. The AEC Q100-012 is the most recognized qualification certificate in industry, which specifies the reliability of this type of device. This application report describes the AEC Q100-012 specification and provides the test method and results for the TPS1H100-Q1 device, a smart high-side switch from Texas Instruments.
