Description
The WT7502V 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 V33, V5 and VCC input voltage level. The Under Voltage
Detector (UVD) monitors V33, V5 and VCC input voltage level. When OVD or UVD detect the fault
voltage level, the FPOB is latched HIGH and PGO go low. When PGI detect the fault voltage level, the
FPOB would be kept LOW 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 PGI and OVD and UVD detect the right voltage level, the power good output (PGO) will be
issue.
--FEATURES:
• The Over Voltage Detector (OVD) monitors V33, V5 and VCC input voltage.
• The Under Voltage Detector (UVD) monitors V33, V5 and VCC input voltage.
• Both of the power good output (PGO) and fault protection latch (FPOB) are Open Drain Output.
• 75 ms time delay for UVD.
• 300 ms time delay for PGO.
• 38 ms for PSONB input signal De–bounce.
• 73 us for PGI and UVD internal signal De–glitches.
• 55 us for OVD internal signal De–glitches.
• 2.4 ms time delay for PSONB turn-off FPOB.
• The UVD would been disabled when PGI < 0.95V
