WT7513
GENERAL DESCRIPTION
The WT7513 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 Voltage Detector(OVD) monitors 3.3V, 5V, 12V input voltage level. The Over Current
Detector (OCD) monitor IS33, IS5, IS12 input current sense :
(1).When OVD or OCD detect the fault voltage level or current sense, the FPOB is latched HIGH.
The PSONB will resets the fault protection latch from LOW to HIGH.
(2).When OVD and OCD and UVD detect the right voltage level, the power good output(PGO) from
LOW to HIGH will be issue.
Add an external resistor between RI pin and GND pin to get an accurate current IRI.
FEATURES
The Over Voltage Detector(OVD) monitors 3.3V, 5V, 12V input voltage level.
The Over Current Detector (OCD) monitor IS33, IS5, IS12 input current sense.
Provide OVD/OCD and lock out for input voltage 3.3V, 5V, 12V
Both of the power good output(PGO) & fault protection latch(FPOB) with Open Drain Output Stage.
300 ms time delay for PGO.
38 ms for PSONB input signal Debounce.
73 us for internal signal De-glitches.
1.2 ms time delay for PSONB turn-off FPOB.
