WT7502 - PC POWER SUPPLY SUPERVISOR

Description

The WT7502 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.

Features

  • The Over / Under Voltage Detector (OVD / 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 / UVD internal signal De.
  • glitches.
  • 55 us for OVD internal signal De.
  • glitches.
  • 3.5 ms time delay for PSONB turn.
