The CXLB7386 is a complete constant-current/constant-

voltage linear charger for single cell lithium-ion batteries.

Its ThinSOT package and low external component count

make the CXLB7386 ideally suited for portable applications.

Furthermore, the CXLB7386 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 CXLB7386 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 CXLB7386 automatically enters a low current

state, dropping the battery drain current to less than 2μA.

The CXLB7386 can be put into shutdown mode, reducing

the supply current to 25μA.

Other features include charge current monitor,

undervoltage lockout, automatic recharge and a status pin

to indicate charge termination and the presence of an input

voltage.
