GENERAL DESCRIPTION
The WT7527V provides protection circuits, power good output (PGO), fault protection latch (FPOB), and a protection detector function (PSONB) control. It can minimize external components of switching power supply systems in personal computer.
The Over Voltage Detector (OVD) monitors VX, V33, V5, V12A and V12B input voltage level. The Under Voltage Detector (UVD) monitors V33, V5, V12A and V12B input voltage level. The Over Current Detector (OCD) monitor I33&V33, I5&V5, I12A&V12A and I12B&V12B input current sense. The pin VX provides an extra protection function. When OVD or UVD or OCD or VX detect the fault voltage level, the FPOB is latched HIGH and PGO go low. The latch can be reset by PSONB go HIGH. There is 4 ms delay time for PSONB turn off FPOB.
When OVD and UVD and OCD detect the right voltage level, the power good output (PGO) will be issue.
FEATURES
? The Over Voltage Detector (OVD) monitors VX, V33, V5, V12A and V12B input voltage.
? The Under Voltage Detector (UVD) monitors V33, V5, V12A and V12B input voltage.
? The Over Current Detector (OCD) monitors I33&33, I5&V5, I12A&V12A and I12B&V12B input pins.
? The VX > 1.2V provide an extra protection.
? Both of the power good output (PGO) and fault protection latch (FPOB) are Open Drain Output.
