     The CXLB7260 is a complete constant current & constant voltage linear charger for single cell 

lithium-ion batteries. Its SOT package and low  external component count make the CXLB7260 ideally

 suited for portable applications.

        Furthermore, the  CXLB7260 is specifically designed to work within USB power specifications.

No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET

 architecture. Thermal feedback regulates the charge current to limit the die temperature during high

 power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge 

current can be programmed externally with a single resistor. The CXLB7260 automatically terminates

 the charge cycle when the charge current drops to 1/10th the programmed value after the final float

 voltage is reached.

           When the input supply (wall adapter or USB supply) is removed, the CXLB7260  automatically

enters a low current state, dropping the battery drain current to less than 2uA. The CXLB7260 can  be 

put into shutdown mode, reducing the supply current to 50uA.

            Other features include Battery temperature monitor, under-voltage lockout, automatic recharge 

and two status pins to indicate charge and charge termination.
