Figure 3-4 and Figure 3-5 illustrate how the PMP23389 behaves under short-circuit protection. Output across J4 was shorted momentarily in order capture meaningful data on oscilloscope to illustrate that short-circuit protection functions effectively as the output voltage returns to the steady state. The short-circuit protection is leveraged by the FAULT pin of the TPS7H5002-SP, which is an optional functionality.
