一,产品概述(General Description)
CXLB7251 是一个完整的单片锂离子<a href="http://www.jtm-ic.com/a/xinwenzhongxin/xinpinjishu/" target="_blank" style="padding: 0px; margin: 0px; color: rgb(37, 110, 177); text-decoration: none;">电池恒流/恒压线性<a href="http://www.jtm-ic.com/a/chanpinzhongxin/chanpinzhonglei/jichengdianlu_IC/" target="_blank" style="padding: 0px; margin: 0px; color: rgb(37, 110, 177); text-decoration: none;">电源管理芯片，其 SOT 封装和极少的外围元件非常适合应用于便携式产品，而且 CXLB7251 专门设计适用于 USB 的供电规格。基于内部 MOSFET结构，不需要外部感应电阻和隔离二极管，当外部环境温度过高或在大功率工作时，热反馈可以调节充电<a href="http://www.jtm-ic.com/a/xinwenzhongxin/" target="_blank" style="padding: 0px; margin: 0px; color: rgb(37, 110, 177); text-decoration: none;">电流以降低<a href="http://www.jtm-ic.com/a/xinwenzhongxin/xingyexinwen/2015/0707/11.html" target="_blank" style="padding: 0px; margin: 0px; color: rgb(37, 110, 177); text-decoration: none;">芯片温度。充电电压被固定在4.2V，充电<a href="http://www.jtm-ic.com/a/xinwenzhongxin/" target="_blank" style="padding: 0px; margin: 0px; color: rgb(37, 110, 177); text-decoration: none;">电流可通过外部电阻设置。当充电电流在达到最终浮充电压之后降至设定值 1/10 时，CXLB7251 将自动终止充电循环。当输入端（适配器或USB电源）拔掉后，CXLB7251自动进入低电流状态，电池漏电流将降到2μA以下。<br style="padding: 0px; margin: 0px;"/> CXLB7251还可被设置于停止工作状态，使电源电流降到25μA。其余特性包括：充电电流监测，欠压锁闭，自动再充电和状态引脚以显示充电结束。<br style="padding: 0px; margin: 0px;"/>二</span>.产品特点(Features)
