Description

The UTC3511 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.

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. When OVD or UVD detect the fault voltage level, the FPL_N is latched HIGH and PGO goes LOW. The latch can be reset by PDON_N going HIGH. There is 2.4ms delay time for PDON_N turning off FPL_N.

When OVD and UVD detect the right voltage level, the power good output (PGO) will be issue.
