NAME
FUNCTION
IN
FLAG
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.
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.
ON
Active-Low, Switch-On Input.
Drive ON low to turn on the switch.
ON
Active-High, Switch-On Input.
Drive ON high to turn on the switch.
GND Ground
SETI
Overload Current Limit Adjust.
Connect a resistor from SETI to
ground to program the
overcurrent limit. Do not connect
any capacitance larger than 20pF
to SETI.
