The Over / Under Voltage Detector (OVD / UVD) monitors 3.3V, 5V, 12V input voltage level.
The Over Current Detector (OCD) monitors IS33, IS5, IS12 input current sense.
Both of the power good output (PGO) and fault protection latch (FPOB) are Open Drain Output.
75 / 300 ms time delay for UVD.
300 ms time delay for PGO.
38 ms for PSONB input signal De鈥揵ounce.
73 us for internal signal De鈥揼litches.
2.4 ms time delay for PSONB turn-off FPOB.
