The cxlb7338 is a single lithium-ion battery constant current/constant voltage linear charger The simple external application circuit is very suitable for portable device application

The cxlb7338 is a single lithium-ion battery constant current / constant voltage linear charger. The simple external application circuit is very suitable for portable device application, suitable for USB power supply and adapter power supply. The internal anti reverse charging circuit is adopted, without external isolation diode. Thermal feedback can adjust the charging current automatically, so as to limit the chip temperature under high power operation or high ambient temperature conditions.
The charging cut-off voltage of cxlb7338 is 4.2V, and the charging current can be set through external resistance. When the charging current drops to 1 / 10 of the set value, the cxlb7338 will automatically end the charging process. When the input voltage is removed, the cxlb7338 will automatically enter the low current standby state and reduce the standby current to less than 1uA. The cxlb7338 can also be placed in shutdown mode when there is input power, thus reducing the working current to 40ua

   CXLB7338 是一款单节锂离子电池恒流/恒压线性充电器,简单的外部应用电路非常适合便携式设备应用,适合USB电源和适配器电源工作,内部采用防倒充电路,不需要外部隔离二极管。热反馈可对充电电流进行自动调节,以便在大功率操作或高环境温度条件下对芯片温度加以限制。mhQ嘉泰姆

   CXLB7338充电截止电压为4.2V,充电电流可通过外部电阻进行设置。当充电电流降至设定值的1/10 时,CXLB7338 将自动结束充电过程。当输入电压被移掉后,CXLB7338 自动进入低电流待机状态,将待机电流降至1uA 以下。CXLB7338 在有输入电源时也可置于停机模式,从而将工作电流降至40uA。mhQ嘉泰姆
