一,产品概述(General Description)      QfS嘉泰姆
QfS嘉泰姆
   The CXLB7201 CXLB7201B is a complete constant-current constant-voltageQfS嘉泰姆

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

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

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

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

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

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

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

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

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