一,产品概述(General Description)      44z嘉泰姆
44z嘉泰姆
   The CXLB7202C CXLB7202 is a complete constant-current/constant voltage44z嘉泰姆

 linear charger for  single cell lithium-ion batteries. Its package and low external 44z嘉泰姆

component count make the CXLB7202C CXLB7202 ideally suited for portable applications.Furthermore, theCXLB7202C CXLB7202 is specifically designed to 44z嘉泰姆

work within USB power specifications. No external sense resistor is needed, and44z嘉泰姆

no blocking diode is required due to the internal MOSFET architecture. The 44z嘉泰姆

charge voltage is fixed at 4.2V, and the charge current can be programmed 44z嘉泰姆

externally with a single resistor.44z嘉泰姆
    The CXLB7202C CXLB7202 automatically terminates the charge cycle when44z嘉泰姆

the charge current drops to 1/10th the programmed value after the final float 44z嘉泰姆

voltage is reached.44z嘉泰姆
     The CXLB7202C CXLB7202 converters are available in the industry standard44z嘉泰姆

 DFN3*3-10L power packages (or upon request).44z嘉泰姆
