| 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. To turn off the power supply, the PSON signal is set from low to high with the delay time 48ms. The PGI circuitry provides a power-down warning signal for PGO. When PGI input is lower than the internal 1.25V reference voltage, the PGO signal is pulled low. FEATURES Two 12V sense input pins: VS12 and VS12B 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 Open-drain output for PGO and FPO pins 300ms power-good delay 300ms turn-on delay for 3.3V, 5V, and two 12V 2.8ms PSON control to FPO turn-off delay 48ms PSON control delay No lockup during the fast AC power on/off Wide supply voltage range from 4V to 15V DESCRIPTION SG6516 is designed to provide the voltage and current supervisor function, remote on/off (PSON) function, TYPICAL APPLICATION (c) System General Corp.

Version 1.0.1 (IAO33.0029.B1) -8- www.sg.com.tw * www.fairchildsemi.com September 24, 2007 Product Specification PC Power Supply Supervisors SG6516 APPLICATION NOTE Over-Current Protection (OCP) The SG6516 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 (5mV). The sink currents of IS33, IS5, and IS12 are eight times the current at the RI pin. The current at the RI pin is VRI/RI. Below is an example demonstrating how to set OCP. If: I1 * R1>(IRI * 8) * R2, then OCP active. To select an R2 resistor: If R1=5m, RI=30K, and OCP protection level is 35A, then R2 = (I1 * R1) / (IRI * 8) = (35A * 5m) / {(1.25V/30K) * 8} = 525 (2) (3) (4) (5) (1) (c) System General Corp.
