Description
The HY510N is PC Power Supply Supervisor. A PC power supply supervisor, also known as a power supply supervisor IC or PSU supervisor, is an integrated circuit (IC) or semiconductor device designed to monitor and control the power supply unit (PSU) in a personal computer or other electronic devices. These supervisors play a crucial role in ensuring the proper operation, safety, and reliability of the power supply and the overall system.
The device provides protection circuits, power good output (PGO), fault protection latch (FPL_N), and a protection detector function (PDON_N) 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 Under Voltage Detector (UVD) monitors 3.3V, 5V input voltage level. When OVD or UVD detect the fault voltage level, the FPL_N is latched HIGH and PGO go low. The latch can be reset by PDON_N goo HIGH.
