DESCRIPTION
NAME
NO.
AUX
10
O
Fixed 5.1-V boost converter output. Connect a low-ESR ceramic capacitor from AUX to PGND.
EN
4
I
Enable input for boost converter. Tie to IN to enable.
ENUSB
7
I
Enable input for the USB switch. Tie to IN or AUX to enable.
FAULT
8
O
Active-low USB fault indicator (open-drain)
GND
5
P
Control/logic ground. Must be tied to PGND close to the IC externally.
ILIM
6
I
Program the nominal USB-switch current-limit threshold with a resistor to GND.
IN
3
I
Input supply voltage for boost converter
PGND
2
P
Source connection for the internal low-side boost-converter power switch. Connect to GND with a
low-impedance connection to the input and output capacitors.
SW
1
P
Boost and rectifying switch input. This node is switched between PGND and AUX. Connect the boost
inductor from IN to SW.
USB
9
O
Output of the USB power switch. Connect to the USB port.
Thermal
—
Must be soldered to achieve appropriate power dissipation. Connect to GND.

I = input; O = output; P = power
AUX
AUX is the boost converter output and provides power to the USB switch and to any additional load connected to
AUX. Internal feedback regulates AUX to 5.1 V. Connect a 22-mF ceramic capacitor from AUX to PGND to filter
the boost converter output. See the Component Recommendations section for further details. Additional external
load can be connected to AUX as long as the total current drawn by the USB switch and external load does not
overload the boost converter. See the Determining the Maximum Allowable AUX and USB Current section for
details.
EN
EN is a logic-level input that enables the boost converter. Pull EN above 1 V to enable the device and below 0.7
V to disable the device. EN also disables the USB switch, because the USB switch cannot be run when the
boost converter is disabled.
ENUSB
ENUSB is a logic-level input that enables the USB switch. Pull ENUSB above 1 V to enable the USB switch and
below 0.7 V to disable the USB switch. ENUSB only enables the USB switch. The boost converter is
independent of ENUSB and continues to operate even when ENUSB disables the USB switch.
