WT7513

Weltrend Semiconductor, Inc. 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/O...
