Description

EN

INPUT

Enable input, logic low/high (i.e. EN or EN) turns on power switch

GND

POWER

Ground connection;

IN

POWER

Power−switch input voltage; connect a 1 mF or greater ceramic capacitor from IN to GND as close as

possible to the IC.

FLAG

OUTPUT

Active−low open−drain output, asserted during overcurrent, overtemperature or reverse−voltage condi-

tions. Connect a 10 kW or greater resistor pull−up, otherwise leave unconnected.

OUT

OUTPUT

Power−switch output; connect a 1 mF ceramic capacitor from OUT to GND as close as possible to the IC

is recommended. A 1 mF or greater ceramic capacitor from OUT to GND must be connected if the USB

requirement (i.e.120 mF capacitor minimum) is not met.
