Overview

The WT7525 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 and V12B input voltage level.
  • The Over Current Detector (OCD) monitors IS33, IS5, IS12A and IS12B 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 internal signal De-glitches.
  • 2.4 ms time delay for PSONB turn-off FPOB.
