1 3-Channel Supervisor IC for Power Supply Features Over-voltage protection and lockout Under-voltage protection and lockout Open drain power good output signal Built-in 300mS delay for power good 38mS de-bounce for PSON/ control 73uS de-bounce for noise immunity Wide power supply range Applications PC power supply LCD TV power supply Description GR8313 is designed to monitor the outputs of switching power supply and generate the power good signal to inform the system. There are three important functions of GR8313: over-voltage protection, under-voltage protection and power good signal generating. 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 and 12V to protect the power supply and system. When power supply is ready or going to shutdown, power good signal generating notifies personal computers; it provides a reliable power supply environment for system.
