     CXLB7377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。因为能选择给LIM端子输入低电平时100mA(MAX.)及输入高电平时500mA(MAX.)的高精度充电电流，适用于从USB提供充电的应用目的。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 CXLB7377 series is a constant-current/constant-voltage linear charger IC for single cell Lithium-ion and Lithium polymer batteries. The CXLB7377 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. As it is possible to select a highly accurate charge current of either 100mA (MAX.) for L level input to the LIM pin or 500mA (MAX.) for H level, the series is ideal for applications where the charge is from USB. The series’ charge status output pin, /CHG pin, is capable of checking the IC’s charging state via connection to an external LED.kES嘉泰姆
