Product Specification PC Power Supply Supervisors SG6520 power good (PGO) indicator function, and fault protection (FPO) function for switching power systems. For supervisor function, it provides the 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 is decreasing to 2.3V, 3.5V and 9V respectively, the under voltage protection (UVP) function will be enabled. FPO will be 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.
