The LX2205 is a complete single
cell Lithium Ion or Lithium Polymer
battery charger and power source
manager. In addition to battery
charging, power flow control is
provided from up to three sources: a
wall adapter, a standard USB power
plug or the battery.
The battery charge current and
termination current are independently
adjustable. The controller also
includes status indicators which show
when the controller is powered by an
external adapter in addition to charge
in progress, and charge completed.
The USB input is current limited at
two logically selectable levels (100mA
and 500mA). When powered by a USB
input, the battery is charged with the
excess USB current that is not
consumed by the system load. If the
load exceeds the USB current limit, the
battery will discharge to assist the USB
power source to power the load. The
controller can logically suspend the
USB power to allow the system to
operate from the battery without
loading the USB.
When a wall adapter is applied, it
takes precedent over the USB power
input and disables the USB input to
prevent current flow from the adapter to
the USB port.
