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 and can sink 20mA.
The LX2207 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,
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
batteries.
The LX2207 can use a wall adapter
or USB power source to charge a
single cell Lithium Ion or Lithium
Polymer battery. There are three logic
selectable and programmable charge
current levels: the high charge
programming level is typically set for
charging from the adapter, the low
level charge programming level is
typically set to 500mA for USB full
USB charging and 100mA (20%) for
reduced level USB charging.
In addition to setting the high-level
charge current, the HCP programming
resistor also sets the termination
current at 10% of the constant current
level and the conditioning current at
5% of the constant current level.
Power status indicators (STAT and
DCOK) can be configured to show
deeply
discharged
