duration exceeds the blanking time, reverse current is detected, thermal shutdown
mode is active, or SETI is connected to ground.
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
asserted. If SETI is unconnected the current limit is at 0mA. Do not connect any
capacitance larger than 20pF to SETI.
Switch Output. Bypass OUT with a 1μF capacitor to GND.
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.
Active-Low, Switch-ON Input. Drive
Active-High, Switch-ON Input. Drive ON high to turn on the switch.
Ground
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.
