GR8313 3-Channel Supervisor IC for Power Supply Features Description Over-voltage protection and lockout GR8313 is designed to monitor the outputs of Under-voltage protection and lockout switching power supply and generate the power Open drain power good output signal good signal to inform the system. There are three Built-in 300mS delay for power good important functions of GR8313: over-voltage 38mS de-bounce for PSON/ control protection, under-voltage protection and power 73uS de-bounce for noise immunity good signal generating. Wide power supply range Over-voltage protection (OVP) monitors 3.3V, 5V and 12V to protect the power supply and system when one of these supply voltages exceeds their normal operation voltage. Under-voltage protection (UVP) monitors 3.3V, 5V Applications and 12V to protect the power supply and system. PC power supply When power supply is ready or going to shutdown, LCD TV power supply power good signal generating notifies personal computers it provides a reliable power supply environment for system.
