   产品概述 返回TOP3xd嘉泰姆

  The  CXLB73103 is a complete constant-current/constant voltage linear charger for single cell lithium-ion batteries. Its package and low external component count make the CXLB73103 ideally suited for portable applications. Furthermore, the  CXLB73103 is specifically designed to work within USB power specifications. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor.The  CXLB73103 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.The  CXLB73103 converters are available in the industry standard SOT-23-6L power packages (or upon request).CXLB73103是完整的恒流/恒压单节线性锂离子电池充电器。它的包和较低的外部组件使计数在USB电源设计工作规范。不需要外部检测电阻,没有由于内部阻塞二极管是必需的MOSFET的架构。充电电压是固定在4.2 v,电流可以收费在外部编程一个电阻器。充电周期电流下降的时候出现1/10th最后浮动后的程序价值电压。封装SOT-23-6L。
