WT7522 : The WT7522 is a pulse–width modulation (PWM) control circuit with complete protection circuits for used in the SMPS (Switched Mode Power Supply). It contains various functions, which are Over Voltage Protection, Under Voltage Protection, Power Good Output (PG), Remote On/Off control, Opamp and etc. It can minimize external components of switching power supply systems in personal computer. Over Voltage Protection (OVP) monitors 3.3V, 5V, 12V and PT input voltage level. Under Voltage Protection (UVP) monitors 3.3V, 5V, 12V and one negative voltage input voltage level. Power Good Output monitors the voltage level of power supply. FEATURES • Complete PWM Control and Protection Circuitry • Over .

WT7525 : The WT7525 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 / Under Voltage Detector (OVD / UVD) monitors V33, V5, V12A and V12B input voltage level. The Over Current Detector (OCD) monitor IS33, IS5, IS12A and IS12B input current sense. When OVD or UVD or OCD 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 2.4 ms delay time for PSONB turn off FPOB. When OVD and UVD and OCD detect the right voltage level, the power good output (PGO.

WT7525Y : The WT7525Y 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 / Under Voltage Detector (OVD / UVD) monitors V33, V5, V12A, V12B and V12C input voltage level. The Over Current Detector (OCD) monitor IS33, IS5, IS12A, IS12B and IS12C input current sense. When OVD or UVD or OCD detect the fault voltage level, the FPOB is latched HIGH and PGO go l.

WT7527 : The WT7527 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.
