NAME
FUNCTION
1, 6
N.C.
No Connection. Not internally connected. Connect N.C. to GND or leave unconnected.
2
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.
3
SETI
Overload-Current Limit Adjust. 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. If SETI is unconnected the current limit is at 0mA. Do not connect any
capacitance larger than 20pF to SETI.
4
OUT
Switch Output. Bypass OUT with a 1μF capacitor to GND.
5
IN
Power Input. Bypass IN with a 1μF ceramic capacitor to GND. Use higher
capacitance if necessary to prevent large load transients from pulling down the
supply voltage.
7
ON
Active-Low, Switch-ON Input. Drive
ON low to turn on the switch.
7
ON
Active-High, Switch-ON Input. Drive ON high to turn on the switch.
8
GND
Ground
—
EP
Exposed Pad. Internally connected to GND. For enhanced thermal dissipation,
connect EP to a large copper ground plane. Do not use EP as the sole ground
connection.
