Description
The HY510N provides protection circuits, power goodoutput (PGO), fault protection latch (FPL_N), and a 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 go low. The latch can be reset by PDON_N goo HIGH. There is 2.4 ms delay time for PDON_N turn off FPL_N. When OVD and UVD detect the right voltage level, the power good output (PGO) will be issue.
