My understanding is that when OVR is driven low, PWR automatically goes low. Is it correct?
My customer's board does not behave that. When OVR pin input low, PWR pin does not go high.
Where should I check on the board?
Thanks,
Tetsuo

Hi Tetsuo,
OVR pin is active low. When overcurrent is detected, PWR (active low) should be disabled (HIGH).
If overcurrent is detected, amber led glows corresponding to that port.
