General 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.
Key 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.
