SG6510X1 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 supervisor function, SG6510X1 provides the over voltage protection (OVP) monitoring for 3.3V, 5V and 12V (12Vvia 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 SG6510X1's functions still can be enabled to protect power supply in case of output short circuit.
