Cxlb7337 is a single lithium-ion battery constant current/constant voltage linear charger. It adopts sop8 package with heat sink at the bottom and simple external application circuit

Cxlb7337 is a single lithium-ion battery constant current / constant voltage linear charger. It adopts sop8 package with heat sink at the bottom and simple external application circuit. It is very suitable for portable device application, suitable for USB power supply and adapter power supply. The internal adopts anti reverse charging circuit and does not need 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 cxlb7337 is 4.35v, and the charging current can be set through external resistance. When the charging current drops to 1 / 10 of the setting value, the cxlb7337 automatically ends the charging process. When the input voltage is removed, the cxlb7337 automatically enters the ultra-low power consumption standby state, reducing the standby current to less than 1uA. The cxlb7337 can also be placed in shutdown mode when there is input power, thus reducing the working current to 40ua.

     CXLB7337是一款单节锂离子电池恒流/恒压线性充电器,采用 底部带散热片的SOP8封装以及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。 CXLB7337充电截止电压为4.35V,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,CXLB7337自 动结束充电过程。 当输入电压被移掉后,CXLB7337自动进入超低功耗待机状 态,将待机电流降至 1uA 以下。CXLB7337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。
