Open-Drain Overcurrent 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.
Forward Current-Limit Adjust Input. Connect a resistor from SETI to GND to
program the overcurrent limit. If SETI is connected to GND, the switch turns off
and FLAG is asserted. Do not leave SETI unconnected or connect any capacitor
larger than 20pF to SETI.
Switch Output. Connect OUT pins 3 and 4 together and bypass OUT to GND with
a 1FF ceramic capacitor as close to the device as possible.
Power Input. Connect IN pins 5 and 6 together and bypass IN to GND with a 1FF
ceramic capacitor as close to the device as possible. If necessary, use higher
capacitance to prevent large load transients from pulling down the supply voltage.
Active-Low Enable Input. Drive EN low to turn on the switch. Drive EN high to turn
off the switch.
Active-High Enable Input. Drive EN high to turn on the switch. Drive EN low to turn
off the switch.
Ground
Exposed Pad. Internally connected to GND. Connect to a large ground plane to
maximize thermal performance. Not intended as an electrical connection point.
