General Description
The WT7502 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.
Key Features
- The Over / Under Voltage Detector (OVD / UVD) monitors V33, V5 and VCC input voltage.
- Both of the power good output (PGO) and fault protection latch (FPOB) are Open Drain Output.
