WT7527 - PC Power Supply Supervisor

Weltrend

Datasheet Details

The WT7527 provides protection circuits, power good output (PGO), fault protection latch (FPOB), and a protection detector function (PSONB) control.

The Over Voltage Detector (OVD) monitors VX, V33, V5, V12A and V12B input voltage.
The Under Voltage Detector (UVD) monitors V33, V5, V12A and V12B input voltage.
The Over Current Detector (OCD) monitors I33&33, I5&V5, I12A&V12A and I12B&V12B input pins.
The VX > 1.2V provide an extra protection.
Both of the power good output (PGO) and fault protection latch (FPOB) are Open Drain Output.
75 / 600 ms time delay for UVD / OCD / VX.
