IN

Power Input. Bypass IN with a

1μF ceramic capacitor to ground.

Use higher capacitance to

prevent large load transients from

pulling down the supply voltage if

necessary. Connect both power

inputs (IN) together.

FLAG

Open-Drain, Overload Indicator

Output.

FLAG goes low when the

overload fault duration exceeds

the blanking time, reverse current

is detected, thermal shutdown

mode is active, or SETI is

connected to ground.
