     CXLB7378系列是用于单节锂离子蓄电池的定电流,定电压线性充电用IC。在内部把蓄电池充电结束时的电压设定为4.2V±0.7%。此外，把连续补充充电电压设定为2.9V±3.0%。连续补充充电模式把提供给蓄电池的电流设定为充电电流的1/10，能实现安全地给蓄电池充电。由外部RSEN电阻可以任意设定充电电流(最大充电电流800mA为止)能适应各种各样的应用目的。备有充电状态输出端子(/CHG)，在外部连接LED能确认充电状态。The CXLB7378 series is a constant-current/constant-voltage linear charger IC for single cell Lithium-ion and Lithium polymer batteries. The CXLB7378 includes a reference voltage source, battery voltage monitor, driver transistor, constant-current/constant-voltage charge circuit, overheat protection circuit and phase compensation circuit. The battery charge termination voltage is internally set to 4.2V ±0.7% and the trickle charge voltage and accuracy is 2.9V ±3%. In trickle charge mode, a safe Lithium-ion and Lithium polymer battery charge is possible because approximately only 1/10 of the full charge current is supplied to the battery. With an external RSEN resistor, the charge current can be set freely up to 800mA (MAX.), therefore, the series is ideal for various battery charge applications. The series’ charge status output pin, /CHG pin, is capable of checking the IC’s charging state while connecting with an external LED.puZ嘉泰姆
