Product Specification PC Power Supply Supervisors SG6516 power-good (PGO) indicator function, and fault protection (FPO) function for switching power systems. For supervisor, it provides over-voltage protection (OVP) for 3.3V, 5V, and two 12V; over-current protection (OCP) for 3.3V, 5V, and two 12V; under-voltage protection (UVP) for 3.3V, 5V, and two 12V. When 3.3V, 5V, or 12V voltage decreases to 2.3V, 3.5V, and 9V respectively, the under-voltage protection (UVP) function is enabled. FPO is set to high to turn off the PWM controller IC. The voltage difference across external current shunt is used for OCP functions. An external resistor can be used to adjust protection threshold. The power supply is turned on after a 48ms delay time when PSON signal is set from high to low.
