CXLB7382单电池锂离子电池的完整恒流/恒压线性充电器可编程充电电流800mA自动充电状态输出引脚C/10充电终止2.9V涓流充电阈值

CXLB7382是一款用于单电池锂离子电池的完整恒流/恒压线性充电器。它的SOT33-5封装和低外部组件数量使CXLB7382非常适合便携式应用。此外,tcxlb7382可以在USB和墙壁适配器中工作。由于内部PMOSFET结构,无需阻塞二极管,并具有防止负电荷电流电路。热反馈调节充电电流,以在高功率运行或高环境温度下限制模具温度。充电电压固定在4.2V,充电电流可通过一个电阻器进行外部编程。达到最终浮充电压后,当充电电流降至编程值的1/10时,CXLB7382自动终止充电循环。CXLB7382其他功能包括电流监视器、欠压锁定、自动充电和指示充电终止的充电状态引脚

The CXLB7382 is a complete constant‐current/constant‐voltage linear charger for single cell lithium‐ion batteries. Its SOT23‐5 package and low external component count make the CXLB7382 ideally suited for portable applications. Furthermore, the TCXLB7382can work within USB and wall adapter. No blocking diode is required due to the internal PMOSFET architecture and have prevent to negative Charge Current Circuit. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The CXLB7382automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached. CXLB7382Other features include current monitor, under voltage lockout, automatic recharge and charge status pin to indicate charge termination.
