General Description

The WT7515 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 / Under Voltage Detector (OVD / UVD) monitors 3.3V, 5V, 12V input voltage level.

Key Features

  • The Over / Under Voltage Detector (OVD / UVD) monitors 3.3V, 5V, 12V input voltage level.
  • The Over Current Detector (OCD) monitors IS33, IS5, IS12 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 m.
