GR8313
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

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.
