一,产品概述(General Description)      Kbq嘉泰姆
Kbq嘉泰姆
   The CXLB7203G is a complete constant current /constant voltage linear charger for single cell lithium-ion batteries.Kbq嘉泰姆

 Its package and low external component count make the CXLB7203G ideally suited for portable applications. Furthermore, Kbq嘉泰姆

the CXLB7203G is specifically designed to work within USB power specifications.Kbq嘉泰姆

The charge voltage is fixed at 4.22V, and the charge current can be programmed externally with a single resistor.Kbq嘉泰姆

 The CXLB7203G automatically terminates the charge cycle when the charge current drops to 1/10th the programmed Kbq嘉泰姆

value after the final float voltage is reached.Kbq嘉泰姆

The CXLB7203G converters are available in the industry standard SOP8-PP power packages (or upon request).Kbq嘉泰姆
