WT7502V Overview
The WT7502V 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 V33, V5 and VCC input voltage level.
WT7502V 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 signal De-glitches
- 2.4 ms time delay for PSONB turn-off FPOB
- The UVD would been disabled when PGI < 0.95V
