Product Specification SG6510X1 PC Power Supply Supervisors 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. FEATURES Over-voltage protection (OVP) for 3.3V, 5V and 12V Under-voltage sense (UVS) and 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 De-bounce 350uS width noise deglitches 2mS UVP De-bounce time 1mS UVS De-bounce 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 DESCRIPTION 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. 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. For supervisor function, it provides the over voltage protection (OVP) monitoring for 3.3V, 5V and 12V (12V TYPICAL APPLICATION 5V 5V SG6510 PGI 1 2 3 PSON © System General Corp.
