CXLB73124

CXLB73124是一款适用于单电池锂离子电池的完整恒流恒压线性充电器。它的PSOP8包和较低的外部组件数量使CXLB73124非常适合便携式应用。此外,CXLB73124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。当达到最终浮充电压后,充电电流降至编程值的1/10时,CXLB73124自动终止充电循环。CXLB73124其他功能包括电流监视器、欠压锁定、自动充电和两个状态引脚,用于指示充电终止和输入电压的存在。

The CXLB73124 is a complete constant - current & constant-voltage linear charger for single cell lithium-ion batteries. Its PSOP8 package and low external component count make the CXLB73124 ideally suited for portable applications. Further more , the CXLB73124 can 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 CXLB73124automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached. CXLB73124Other features include current monitor, under voltage lockout, automatic recharge and two status pin to indicate charge termination and the presence of an input voltage.
