Hi ti team，
I am experiencing automatic shutdown of the MOSFET in my TPS2390 application. I cannot find out why it is shutting down automatically, but I have captured some waveforms that I would like technical support to analyze. We are performing static aging tests. We have also measured the load current waveform, and the current is stable at 26A with no fluctuations (there were no unusual fluctuations in the current when the MOSFET shut down). The limiting resistor is actually set to 1mR.
Channel 1: Gate of MOS Channel 2: EN of TPS2390 Channel 3: Flttime pin of TPS2390 Channel 4: Gate of TPS2390 with 48V supply has a dropout, and it occurs before the Flttime waveform.
