... Functional Description The SG6520A provides over-current protection for the 3.3V, 5V, and two 12V rails. Whenever an OCP condition occurs at any of the voltage rails, PGO is LOW and FPO is open. The internal OCP comparators have a very small offset voltage ( ± 3mV). The sink currents of IS33, IS5, and IS12 are eight times the current at the RI pin ...
