PGOOD/PON LEDs not switching off - Circuit Sword

Post by cowdog360 » Thu Mar 15, 2018 7:24 pm

Here's a wierd one. The Blue and Red PGOOD/PON LED's turn on when I plug the USB-C in for charging (charging green LED lights up too). However, when I unplug the USB connector, the PGOOD/PON LED's don't turn off. Now if I quickly turn the unit on and off, they then switch off. But the second I plug in USB, same issue again.

The wierd part is I have another CSO board that doesn't have this behavior.

Any ideas, or is there some defective hardware here?
