FLAG
Fault-Present-Indicator Output.
FLAG
is an open-drain output and goes low when the
overload fault duration exceeds the blanking time, reverse current is detected, or the device
is in thermal shutdown. Connect
FLAG
to IN with a 5k
resistor. For latch-off (MAX4766B)
versions, the switch is turned off and
FLAG
output goes low after the blanking time. For the
continuous version (MAX4766C),
FLAG
does not wait for the blanking time and goes low as
soon as the current-limit threshold is reached.

SETI
Current-Limit Adjust. To program the current limit, connect a resistor from SETI to ground.
See the
Setting the Current Limit
Section for more detail. Shorting SETI to ground sets the
device for maximum current limit of 1.5A.
