10 / 13 page Product Specification PC Power Supply Supervisors SG6520 © System General Corp. - 10 - www.sg.com.tw • www.fairchildsemi.com Version 1.0.1 (IAO33.0041.B0) September 28, 2007 APPLICATION NOTE Over Current Protection (OCP) The SG6520 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 will be low and FPO will be open. The internal OCP comparators have a very small offset voltage (±5mV). The sink currents of IS33, IS5, IS12 and IS12B are 8 times the current at the RI pin. The current at the RI pin is VRI/Ri. Here is an example demonstrating how to set the over current protection. If I1*R1>(IRI*8)*R2, than OCP active. How to select R2 Resistor: If R1 =5mΩ, Ri=30K, OCP Protection Level is 35A, than R2 = (I1*R1)/(IRI*8) = (35A*5mΩ)/{(1.25V/30K)*8} = 525Ω |
