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

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

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

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

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

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

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

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

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

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