There is a lot of advantage in taking the time to do the experiments and not just assume the causes of an effect. Most of the time inrush current problems are caused by capacitors charging in a load that looks initially like a short circuit. Since your circuit doesn&#39;t have capacitors it looks like you are probably correct is deciding that it is a higher slew rate that is causing the problem. The over load detection on your power supply must be fast enough to see a potential over current situation and react to it even before the current becomes critical.</p><p>&nbsp;</p><p>John</p><img src="https://community.element14.com/aggbug?PostID=9909&AppID=14&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/roadtest/b/blog/posts/using-the-msox3034t-to-characterize-in-rush-currentTue, 22 Sep 2020 18:46:26 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1db04fa3-7eaa-4bfd-a12c-faf04162a83eDAB1<p>Very good experiment to test the scope.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=9909&AppID=14&AppType=Weblog&ContentType=0" width="1" height="1">
