The CXLB7386 is a complete constant-current/constant-7Vk嘉泰姆

voltage linear charger for single cell lithium-ion batteries.7Vk嘉泰姆

Its ThinSOT package and low external component count7Vk嘉泰姆

make the CXLB7386 ideally suited for portable applications.7Vk嘉泰姆

Furthermore, the CXLB7386 is specifically designed to7Vk嘉泰姆

work within USB power specifications.7Vk嘉泰姆

No external sense resistor is needed, and no blocking7Vk嘉泰姆

diode is required due to the internal MOSFET architecture.7Vk嘉泰姆

Thermal feedback regulates the charge current to limit the7Vk嘉泰姆

die temperature during high power operation or high7Vk嘉泰姆

ambient temperature. The charge voltage is fixed at 4.2V,7Vk嘉泰姆

and the charge current can be programmed externally with7Vk嘉泰姆

a single resistor. The CXLB7386 automatically terminates7Vk嘉泰姆

the charge cycle when the charge current drops to 1/10th7Vk嘉泰姆

the programmed value after the final float voltage is7Vk嘉泰姆

reached.7Vk嘉泰姆

When the input supply (wall adapter or USB supply) is7Vk嘉泰姆

removed, the CXLB7386 automatically enters a low current7Vk嘉泰姆

state, dropping the battery drain current to less than 2μA.7Vk嘉泰姆

The CXLB7386 can be put into shutdown mode, reducing7Vk嘉泰姆

the supply current to 25μA.7Vk嘉泰姆

Other features include charge current monitor,7Vk嘉泰姆

undervoltage lockout, automatic recharge and a status pin7Vk嘉泰姆

to indicate charge termination and the presence of an input7Vk嘉泰姆

voltage.7Vk嘉泰姆
