Dear ADI Expert,
My customer has 2 questions about the ADM1272 short circuit and EFAULT level and behavior.
1. ADM1272 not only detects Vsense when the output is short-circuited but also detects VDS, right? How much VDS voltage will be judged as output short by ADM1272?
2. The ADM1272 datasheet writes that the EFAULT pin reaches 1V and the FET will be turned off. My customer increases the current by E-load to test OCP. The FET will not turn off until EFAULT reaches 1.78V(As below in picture1 & 2). Why is it not 1V? Why is it very different from the calculation tool?
