UTC3511 Overview
The UTC 3511 provides protection circuits, power good output (PGO), fault protection latch (FPL_N), and protection detector function (PDON_N) control. It can minimize external ponents of switching power supply systems in personal puter. The Over Voltage Detector (OVD) monitors 3.3V, 5V, 12V input voltage level.
UTC3511 Key Features
- The Over Voltage Detector (OVD) monitors 3.3V, 5V, 12V input voltage level
- The Under Voltage Detector (UVD) monitors 3.3V, 5V input voltage level
- Both of the power good output (PGO) and the fault protection latch (FPL_N) are Open Drain Output
- 75 ms time delay for UVD
- 300 ms time delay for PGO
- 38 ms for PDON_N input signal De-bounce
- 73 us for internal signal De-glitches
- 2.4 ms time delay for PDON_N turn-off FPL_N
