SG6510X1 PC Power Supply Supervisors December 2008 SG6510X1 PC Power Supply Supervisors Over-Voltage Protection OVP for 3.3V, 5V, 12V Under-Voltage Sense UVS and Under-Voltage Protection UVP for 3.3V, 5V Open-Drain Output for PGO and FPO Pins 300ms Power-Good Delay 75ms Turn-on Delay for 3.3V and 5V 2.8ms PSON Control to FPO Turn-off Delay 38ms /38ms PSON Control Debounce 350us Width Noise Deglitches 2ms UVP Debounce Time 1ms UVS Debounce Time No Lockup During the Fast AC Power On/Off Brownout Protection Function for 3.3V and 5V Wide Supply Voltage Range from 4V to 15V SG6510 is designed to provide the voltage supervisor function, remote on/off PSON function, power-good PGO indicator function, and fault protection FPO function for switching power systems. For the supervisor function, it provides the over-voltage protection OVP monitoring for 3.3V, 5V, and 12V via VDD pin under-voltage sense UVS monitoring for 3.3V and 5V and under-voltage protection UVP monitoring for 3.3V and 5V. When 3.3V or 5V voltage is decreasing to 2.8V and 4.2V, respectively, the undervoltage sense UVS function is enabled to reset the PGO signal from high to low. If 3.3V or 5V voltage is further decreasing to 2.5V and 3.6V, respectively, FPO is set high to turn off the PWM controller IC. To achieve better immunity for lighting surge glitch and to prevent accidental power shut down during dynamic loading condition, the debounce time for UVP and UVS is 2ms/1ms, respectively. The deglitch time for OVP is 75µs for better noise immunity. During an AC sag or brownout situation, UVP functions can still be enabled to protect power supply in case of output short circuit. The power supply is turned on after 38ms debounce time when the PSON signal is set from high to low. To turn off the power supply, the PSON signal is set from low to high and the debounce time is 38ms. 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 350us debounce time, the PGO signal is pulled low.

SG6510 is designed to provide the voltage supervisor function, remote on/off PSON function, power-good PGO indicator function, and fault protection FPO function for switching power systems.

For the supervisor function, it provides the over-voltage protection OVP monitoring for 3.3V, 5V, and 12V via VDD pin under-voltage sense UVS monitoring for 3.3V and 5V and under-voltage protection UVP monitoring for 3.3V and 5V. When 3.3V or 5V voltage is decreasing to 2.8V and 4.2V, respectively, the undervoltage sense UVS function is enabled to reset the PGO signal from high to low. If 3.3V or 5V voltage is further decreasing to 2.5V and 3.6V, respectively, FPO is set high to turn off the PWM controller IC. To achieve better immunity for lighting surge glitch and to prevent accidental power shut down during dynamic loading condition, the debounce time for UVP and UVS is 2ms/1ms, respectively. The deglitch time for OVP is 75µs for better noise immunity. During an AC sag or brownout situation, UVP functions can still be enabled to protect power supply in case of output short circuit.

The power supply is turned on after 38ms debounce time when the PSON signal is set from high to low. To turn off the power supply, the PSON signal is set from low to high and the debounce time is 38ms. 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 350us debounce time, the PGO signal is pulled low.
