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.
