WT7525Y
Overview
The WT7525Y 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/Under Voltage Detector (OVD / UVD) monitors V33, V5, V12A, V12B and V12C input voltage.
- The Over Current Detector (OCD) monitors IS33, IS5, IS12A, IS12B and IS12C input current sense.
- Both of the power good output (PGO) and fault protection latch (FPOB) are Open Drain Output.
- 75 / 300 ms time delay for UVD.
- 300 ms time delay for PGO.
- 38 ms for PSONB input signal De-bounce.
- 73 us for PGI/OVD/UVD internal signal De-glitches.
- 1.2 ms for OCD internal signal De-glitches.
- 3.5 ms time delay for PSONB turn-off FPOB. Weltrend Semiconductor, Inc. Page 2 WT7525Y Preliminary release Rev. 0.40
