WT7527V PC POWER SUPPLY SUPERVISOR

WT7527V PC POWER SUPPLY SUPERVISOR

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.

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.
• 75 / 600 ms time delay for UVD / OCD / VX .
• 300 ms time delay for PGO.
• 38 ms for PSONB input signal De
  –bounce.
• 14 us for OVD internal signal De
