DESCRIPTION
The UTC 3511 provides protection circuits, power good output (PGO), fault protection latch (FPL_N), and protection detector function (PDON_N) control.
It can minimize external components of switching power supply systems in personal computer.

FEATURES
* The Over Voltage Detector (OVD) monitors 3.3V, 5V, 12V input voltage level.
* The Under Voltage Detector (UVD) monitors 3.3V, 5V input voltage level.
* Both of the power good output (PGO) and the fault protection latch (FPL_N) are Open Drain Output.
* 75 ms time delay for UVD.
* 300 ms time delay for PGO.
* 38 ms for PDON_N input signal De-bounce.
* 73 us for internal signal De-glitches.
* 2.4 ms time delay for PDON_N turn-off FPL_N.
