Four important functions of PS25A are the followings: over-voltage protection, over-current protection, under-voltage protection and power good signal generating. OVP/UVP (Over-Voltage/Under-Voltage Protection) monitors triple 12V to protect our power supply and PC, FPO/ goes to high when one of these supply voltages exceeds their normal operation voltage range.
