【应用】可编程单节锂电池充电管理IC,支持5V/900mA的功率输出可用于给蓝牙耳机充电
目前,蓝牙耳机由于其无线连接,携带方便的优势,越来越多的消费者都开始选用蓝牙耳机,蓝牙耳机采用的是内置锂电池供电,而锂电池由于其需要反复充放电,其充电和放电都是各需要一颗管理芯片。蓝牙耳机自身体积就有限,内部还要内置锂电池,因此对于其他器件的体积要求就非常严苛,必须在小体积空间内,完成锂电池的充放电管理。
圣邦微的单节锂电池充电管理IC SGM4056,支持最大26.5V电压输入,高电压的优势,使得其可以适配更多的充电器,不仅常规的5V充电器能给耳机充电,9V,12V的快充适配器也能给耳机充电。另外,SGM4056还支持锂电池充电特有的CC/CV充电曲线,锂电池在前期,需要大电流直冲,在接近充满时,转为涓流充电,存在一个CC到CV的转换,SGM4056支持100mA-900mA的可编程充电电流,可通过对锂电池的不同充电阶段,设置不同的充电电流。
SGM4056的应用原理图如下:
图1
SGM4056目前只能支持单节的锂电会充电管理,共有两种封装规格,分别是SOIC-8和TDFN-3×3-8L/TDFN-2×3-8L/TDFN-2×2-8L,其尺寸图如下:
图2
SGM4056特性参数如下:
●用于单节锂离子或聚合物电池的完整充电器;
●集成的传输元件和电流传感器;
●无需外部阻塞二极管;
●低组件数和成本;
●可编程充电电流;
●可编程充电结束电流;
●热保护的充电电流热折返;
●2.55V Trickle Charge Threshold;
●SGM4056-6.8的6.8V输入过压保护;
●SGM4056-10.5的10.5V输入过压保护;
●电源输入的最大电压为26.5V;
●电源存在和充电指示;
●未连接输入电源或禁用充电器时,电池漏电流小于1μA;
●提供绿色TDFN-3×3-8L,TDFN-2×3-8L,TDFN-2×2-8L和SOIC-8(裸露焊盘)封装。
