FP3510
PC POWER SUPPLY SUPERVISOR
GENERAL DESCRIPTION
The FP3510 provides protection circuits, power good output (PGO), fault protection latch (FPO),and a
protection detector function (PSON) 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 FPO is latched HIGH and PGO go low. The latch can be reset
by PSON goo HIGH. There is 2.4 ms delay time for PSON turn off FPO. When OVD and UVD detect
the right voltage level, the power good output (PGO) will be issue.
FEATURES
z The OVD monitors 3.3V, 5V, 12V input voltage level.
z The UVD monitors 3.3V, 5V input voltage level.
z Both of the PGO and FPO are Open Drain Output.
z 75 ms time delay for UVD.
z 300 ms time delay for PGO.
z 38 ms for PSON input signal De–bounce.
z 73 us for internal signal De–glitches.
z 2.4 ms time delay for PSON turn-off FPO.
