SG6513S

Product Specification PC Power Supply Supervisors SG6513/T For supervisor function, it provides the over voltage protection (OVP) monitoring for 3.3V, 5V and 12V; over current (OCP) monitoring for 3.3V, 5V and 12V; under voltage sense (UVS) monitoring for 3.3V, 5V and 12V; under voltage protection (UVP) monitoring for 12V; and over temperature protection (OTP) for SG6513T. When 3.3V, 5V or 12V voltage is decreasing to 2.8V, 4.2V and 9.9V respectively, the under voltage sense (UVS) function will be enabled to reset the PGO signal from high to low. If 12V voltage is further decreasing to 9V, 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. To achieve better immunity for lighting surge glitch and to prevent accidental power shut down during dynamic loading condition, the de-bounce time for UVP/OCP and UVS is 275us/125us ,350us respectively. The deglitch time for OVP is 75uS for better noise immunity. The power supply is turned on after 38mS de-bounce time when PSON signal is set from high to low. To turn off power supply, PSON signal is set from low to high and the de-bounce time is 115mS. The PGI circuitry provides a sufficient power-down warning signal for PGO. When PGI input is lower than the internal 1.2V reference voltage, after 250uS de-bounce time, the PGO signal is pulled low. FEATURES OVERVIEW Over-voltage protection (OVP) for 3.3V, 5V and 12V Over-current protection (OCP) for 3.3V, 5V and 12V Under-voltage sense (UVS) for 3.3V, 5V and 12V Under-voltage protection (UVP) for 12V Open drain output for PGO and FPO pins 300mS power good delay 75mS delay for 3.3V, 5V and 12V power turn on 2.8mS PSON control to FPO turn-off delay 38mS / 115mS PSON control De-bounce 275uS width noise deglitches De-bounce time 125uS for UVP and OCP De-bounce time 350uS for UVS No lockup during the fast AC power on/off Brownout protection function for 12V Wide supply voltage range from 4V to 15V Over-temperature protection (OTP) function DESCRIPTION SG6513 is designed to provide the voltage, current and temperature supervisor function, remote on/off (PSON) function, power good (PGO) indicator function, and fault protection (FPO) function for switching power systems.

For ATX SMPS, it detects AC line voltage through the main transformer. Ground. Fault protection output. Output signal to control the primary PWM IC through a opto-coupler. When FPO is low, the main SMPS is operational. Remote On/Off logic input from CPU or main-board. The power supply will be turned on/off after 38mS / 115mS delay. 12V over current protection sense input. Regarding typical application, this pin is connected to the positive end of a current shunt through one resistor. When the voltage on IS12 is higher than that of VS12 by 5mV, OCP will be enabled. One current sink, 8 x Iref, is used to determine the voltage drop between the positive end of the current shunt and VS12. Adjusting the value of the external resistor can adjust the threshold for OCP accordingly. The operation for IS5 or IS33 is the same. Reference setting. One external resistor Ri connected between RI and GND pin will determine a reference current, Iref = 1.15/Ri, for OTP and OCP programming. Over-temperature protection. Only valid for SG6513T. An NTC thermistor is connected from RT pin to GND. At high temperature, the impedance 5 IS12 Analog input 6 RI Analog input 7 RT(for SG6513T) NC( for SG6513) Analog input of the NTC will decrease and hence the voltage on RT will decrease. When the voltage on RT pin is lower than 0.95V limit, the over-temperature protection will be enabled. The internal pull high current source is equal to 5 x Iref. 8 9 10 11 IS5 IS33 VS12 VS33 Analog input Analog input Analog input Analog input 5V over current protection sense input. 3.3V over current protection sense input. 12V over/under-voltage control sense input. 3.3V over/under-voltage control sense input. © System General Corp.
