CXCH76015单电池锂离子锂聚合物电池全限流恒压充电器自动识别电池极性支持2个LED和闪烁LED方案自动终止充电循环

CXCH76015是一款适用于单电池锂离子和锂聚合物电池的全限流恒压充电器。它的SOT-23-6L封装和低外部组件数使CXCH76015C/D非常适合便携式应用。此外，CXCH76015/D专门设计用于通用旅行充电器。CXCH76015/D有一个内置探测器，可以自动检测插入电池的极性，并以正确的极性对电池充电。充电电压固定在4.22V，达到最终浮充电压后，当充电电流降至14mA时，CXCH76015/D自动终止充电循环。当输入电源断开时，CXCH76015/D自动进入低电流级，使电池放电电流降至小于7毫安。CXCH76015/D可进入关机模式，将电源电流降至30uA。CXCH76015/D支持两个LED驱动器，使客户可以选择哪种方法最适合其各自的应用。内部设置一个LED驱动器，指示IC的电源开/关。另一个LED驱动程序可以驱动一个名为CXCH76015的标准LED或名为CXCH76015的7色LED，这将在应用说明中详细说明。

   CXCH76015C/D is a complete Current-Limit & constant voltage charger for single cell Lithium-ion and Lithium-Polymer batteries. Its SOT-23-6L package and low external component count make CXCH76015C/D ideally suited for portable applications. Furthermore, the CXCH76015/D is specifically designed to work within Universal Travel Charger. CXCH76015/D has a built-in detector that will automatically detect the polarity of the inserted battery and charge the battery at the correct the polarity. The charge voltage is fixed at 4.22V. The CXCH76015/D automatically terminates the charge cycle when the charge current drops to 14mA after the final float voltage is reached. When the input supply is removed, the CXCH76015/D automatically enters a low current stage, dropping the battery drain current to less than 7mA. The CXCH76015/D can be put into shutdown mode, reducing the supply current to 30uA. CXCH76015/D supports two LED drivers that give the customers the option to select which method fit best in their respective applications. One LED driver is internally set to indicate the power on/off of the IC. Another LED driver can either drive a standard LED named CXCH76015 or 7-color LED named CXCH76015, which will be explained in detail in the application notes.
