Overview
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.
