I have trouble enabling the overcurrent fault detection in the SLG46580V. When increasing the load at the output I can see the output current limits to around 200mA. When in the current limited state I am expecting the nFAULT signal to go low, but it stays high. If completely short-circuiting the output so the voltage drops below 0.5V, the nFAULT signal go low as expected.
I have tried both high power and low power mode.
Am I missing something, do you need to enable any additional circuits in order to activate the nFAULT overcurrent detection?
FJ,
I just made the testing using my equipment and I replicated this issue. I still have to make some further testing on this issue
