Cxlb73106 is a perfect single-chip lithium-ion battery constant current / constant voltage linear power management chip, its sot package and few peripheral components are very suitable for portable products, and cxlb73106 is specially designed for USB power supply specifications. Based on the internal MOSFET structure, there is no need for external induction resistance and blocking diode. When the external environment temperature is too high or working at high power, the thermal feedback can adjust the charging current to reduce the chip temperature. The charging voltage is limited to 4.2V, and the charging current can be adjusted by external resistance. When the charging current drops to 1 / 10 of the set value after reaching the predetermined charging voltage, the cxlb73106 automatically ends the charging process. When the input terminal (adapter or USB power supply) is unplugged, the cxlb73106 will automatically enter the low current state, and the battery leakage current will drop below 2 μ a. The cxlb73106 can also be set to stop working to reduce the power supply current to 25 μ a. Charging current monitoring, input low voltage locking, automatic recharging, full charging and start charging marks

产品概述 返回TOP
CXLB73106是一个完善的单片锂离子电池恒流/恒压线性电源管理芯片，其SOT封装和极少的外围元件非常适合应用于便携式产品，而且CXLB73106专门设计适用于USB的供电规格。基于内部MOSFET结构，不需要外部感应电阻和阻塞二极管，当外部环境温度过高或在大功率工作时，热反馈可以调节充电电流以降低芯片温度。充电电压被限定在4.2V，充电电流可通过外部电阻调整。在达到预定充电电压后，充电电流降低到设定值的1/10时，CXLB73106自动结束充电过程。 当输入端（适配器或USB电源）拔掉后，CXLB73106自动进入低电流状态，电池漏电流将降到2μA以下。CXLB73106还可被设置于停止工作状态，使电源电流降到25μA。 充电电流监测，输入低电压锁闭，自动重新充电和充电已满及开始充电的标志。
