1A Li-Ion Battery Charger with Power Source Management

PRODUCTION DATA SHEET

The LX2205 is a complete single two logically selectable levels 100mA
cell Lithium Ion or Lithium Polymer and 500mA . When powered by a USB
battery charger and power source input, the battery is charged with the
manager. In addition to battery excess USB current that is not
charging, power flow control is consumed by the system load. If the
provided from up to three sources a load exceeds the USB current limit, the
wall adapter, a standard USB power battery will discharge to assist the USB
plug or the battery.
power source to power the load. The

The battery charge current and controller can logically suspend the
termination current are independently USB power to allow the system to
adjustable. The controller also operate from the battery without
includes status indicators which show loading the USB.
when the controller is powered by an When a wall adapter is applied, it
external adapter in addition to charge takes precedent over the USB power
in progress, and charge completed. input and disables the USB input to

The USB input is current limited at prevent current flow from the adapter to
the USB port.
