FP3510

Technology 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 inte...
