8.2.2.2 AEC Q100-012 Test Grade A Certification
Short-circuit reliability is critical for smart high-side power switch devices. The AEC-Q100-012 standard is used to
determine the reliability of the devices when operating in a continuous short-circuit condition. Different grade
levels are specified according to the pass cycles. This device is qualified with the highest level, Grade A, 1
million times short-to-GND certification.
Three test modes are defined in the AEC Q100-012 standard. See Table 3 for cold repetitive short-circuit test –
long pulse, cold repetitive short-circuit test – short pulse, and hot repetitive short-circuit test.
