一,产品概述(General Description)      

   The CXLB7201 CXLB7201B is a complete constant-current constant-voltageQFX嘉泰姆

 linear charger for single cell lithium-ion batteries. Its package and low external QFX嘉泰姆

component count make the CXLB7201 CXLB7201B ideally suitedfor portable applications.Furthermore,theCXLB7201 CXLB7201B is specifically QFX嘉泰姆

designed to work within USB power specifications.No external sense resistor is QFX嘉泰姆

needed, and no blocking diode is required due to the internal MOSFET QFX嘉泰姆

architecture. The charge voltage isfixed at 4.2V, and the charge current can QFX嘉泰姆

be programmed externally with a single resistor.
     The CXLB7201 CXLB7201B automatically terminates the charge cycle when QFX嘉泰姆

the charge current drops to 1/10th the programmed value after the final float QFX嘉泰姆

voltage is reached.
    The CXLB7201 CXLB7201B converters are available in the industry standardQFX嘉泰姆

 SOT-23-5L power packages (or upon request).
