SG6510X1 Datasheet Pc Power Supply Supervisors

Manufacturer: System General

Overview: Product Specification PC Power Supply Supervisors SG6510X1 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 under voltage sense (UVS) function will be 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 will be set to 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 de-bounce time for UVP and UVS is 2mS/1mS respectively. The deglitch time for OVP is 75uS for better noise immunity. During AC sag or brownout situation, the UVP functions still can be enabled to protect power supply in case of output short circuit. 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 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 de-bounce time, the PGO signal is pulled low.
