Cxlb7369 is a single lithium-ion battery constant current / constant voltage linear charger with excellent performance. The cxlb7369 uses esop8 package with fewer peripheral components, which makes it very suitable for portable products, as well as USB power supply and adapter power supply. Based on the special internal MOSFET architecture and anti reverse charging circuit, cxlb7369 does not need external detection resistor and isolation diode. When the external environment temperature is too high or in high-power applications, thermal feedback can adjust the charging current to reduce the chip temperature. The charging voltage is fixed at 4.3v, while the charging current can be set externally through a resistor. When the charging current drops to 1 / 10 of the set value after reaching the final floating charge voltage, the chip will terminate the charging cycle. When the input voltage is disconnected, the cxlb7369 enters the low current state, and the battery leakage current will drop below 2ua. The cxlb7369 can be set to shutdown mode, when the chip static current drops to 30uA. The cxlb7369 also includes other features: battery temperature monitoring, undervoltage locking, automatic recharging and two status pins to display charging and charging termination.

产品概述 返回TOP
CXLB7369是一款性能优异的单节锂离子电池恒流/恒压线性充电器。CXLB7369采用ESOP8封装配合较少的外围原件使其非常适用于便携式产品,并且适合给USB电源以及适配器电源供电。基于特殊的内部MOSFET架构以及防倒充电路,CXLB7369不需要外接检测电阻和隔离二极管。当外部环境温度过高或者在大功率应用时,热反馈可以调节充电电流以降低芯片温度。充电电压固定在4.3v,而充电电流则可以通过一个电阻器进行外部设置。当充电电流在达到最终浮充电压之后降至设定值的1/10,芯片将终止充电循环。当输入电压断开时,CXLB7369进入低电流状态,电池漏电流将降到2uA以下。CXLB7369可以被设置于停机模式,此时芯片静态电流降至30uA。CXLB7369还包括其他特性:电池温度监测,欠压锁定,自动再充电和两个状态引脚以显示充电和充电终止。
