PIN FUNCTIONS
OUT (Pins 1, 3, 8): Voltage Output. This pin is used to
provide controlled power to a USB device from either
USB V BUS (IN) or the battery (BAT) when the USB is not
present. This pin can also be used as an input for battery
charging when the USB is not present and a wall adapter
is applied to this pin. OUT should be bypassed with at least
4.7μF to GND. Connect Pins 1, 3 and 8 with a resistance
no greater than 10mΩ.
BAT (Pins 2, 4, 5): Connect to a single cell Li-Ion battery.
This pin is used as an output when charging the battery, and
as an input when supplying power to OUT. When the OUT
pin potential drops below the BAT pin potential, an ideal
diode function connects BAT to OUT and prevents V OUT from
dropping more than 50mV below V BAT . A precision internal
resistor divider sets the ?nal ?oat (charging) potential on
this pin. The internal resistor divider is disconnected when
IN and OUT are in undervoltage lockout. Connect Pins 2,
4 and 5 with a resistance no greater than 10mΩ.
IN (Pin 9): Input Supply. Connect to USB supply, V BUS .
Input current to this pin is limited to either 20% or 100% of
the current programmed by the CLPROG pin as determined
by the state of the HPWR pin. The input current limit can
also be disabled by pulling CLDIS high. Charge current (to
BAT pin) supplied through the input is set to the current
programmed by the PROG pin but will be limited by the
input current limit if charge current is set greater than the
input current limit.
CLDIS (Pin 10): Current Limit Disable. This logic input
is used to disable the input current limit programmed by
CLPROG. A voltage greater than 1.2V on the pin will set
the current limit to I IN(MAX) (typically 2.6A). A weak pull-
down current is internally applied to this pin to ensure
it is low at power-up when the input is not being driven
externally.
SUSP (Pin 11): Suspend Mode Input. Pulling this pin
above 1.2V will disable the power path from IN to OUT. The
supply current from IN will be reduced to comply with the
USB speci?cation for Suspend mode. Both the ability to
charge the battery from OUT and the ideal diode function
(from BAT to OUT) will remain active. Suspend mode will
reset the charge timer if V OUT is less than V BAT while in
suspend mode. If V OUT is kept greater than V BAT , such as
when a wall adapter is present, the charge timer will not be
reset when the part is put in suspend. A weak pull-down
current is internally applied to this pin to ensure it is low
at power-up when the pin is not being driven externally.
