WT7527V Overview
The WT7527V provides protection circuits, power good output (PGO), fault protection latch (FPOB), and a protection detector function (PSONB) control. It can minimize external ponents of switching power supply systems in personal puter. The Over Voltage Detector (OVD) monitors VX, V33, V5, V12A and V12B input voltage level.
WT7527V Key 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 VX > 1.2V provide an extra protection
- Both of the power good output (PGO) and fault protection latch (FPOB) are Open Drain Output
