PIN FUNCTION DESCRIPTION
Pin Name Type
Description
EN1
I
Enable 1 input, logic low/high (i.e. EN or EN) turns on power switch.
EN2
I
Enable 2 input, logic low/high (i.e. EN or EN) turns on power switch.
GND
P
Ground connection.
IN
P
Power−switch input voltage; connect a 1 mF or greater ceramic capacitor from IN to GND as close as possible to
the IC.
FLAG1
O
Active−low open−drain output 1, asserted during overcurrent or overtemperature conditions. Connect a 10 kW or
greater resistor pull−up, otherwise leave unconnected.
FLAG2
O
Active−low open−drain output 2, asserted during overcurrent or overtemperature conditions. Connect a 10 kW or
greater resistor pull−up, otherwise leave unconnected.
OUT1
O
Power−switch output1; connect a 1 mF ceramic capacitor from OUT1 to GND, as close as possible to the IC.
This minimum value is recommended for USB requirement in terms of load transient response and strong short
circuits.
OUT2
O
Power−switch output2; connect a 1 mF ceramic capacitor from OUT2 to GND, as close as possible to the IC.
This minimum value is recommended for USB requirement in terms of load transient response and strong short
circuits.
