WT7515 Overview
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.
WT7515 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 ms time delay for PSONB turn-off FPOB
