APPLICATIONS
The LX2206 can be used with a
wall adapter or USB power source to
charge a single cell Lithium Ion or
Lithium Polymer battery. There are
two logic selectable and program-
mable charge current levels which can
be set from anywhere between 50mA
to 1A. The termination current is 1/10
the charge level set by the High Level
Programming Current Pin.
Power status indicators (STAT and
DCOK) can be configured to show
charge in progress, battery fully
charged and external power on. The
STAT pin is capable of sourcing or
sinking 10mA. The DCOK output is
an open drain output.
The LX2206 enters a low quiescent
current sleep mode when power is
removed or when it is logically
shutdown to minimize battery drain.
There are several protection features
which include: under voltage lock out,
inrush current limiting, reverse current
blocking on the IN pin, a thermal loop
to reduce charge current to maintain a
low die temperature, an unsafe battery
temperature charge inhibitor, and
conditioning mode is provided for
deeply discharged batteries.
