思旺推出能够或许主动辨认锂电池极性的LCD驱动IC—SE9120

      June 21^th , 2010–明天, 专业电(dian)(dian)(dian)(dian)(dian)(dian)源办(ban)理(li)IC供(gong)给商北(bei)京(jing)思旺推出SE9120,能够或(huo)许(xu)主动辨认电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)极(ji)性的(de)单(dan)节锂电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)电(dian)(dian)(dian)(dian)(dian)(dian)器LCD驱动IC.☂ SE9120用(yong)(yong)(yong)的(de)是小(xiao)而简略的(de)SOP14或(huo)COB封装情势,并且几近不(bu)须(xu)要任何外部元件就能够或(huo)许(xu)为具备LCD屏(ping)(ping)的(de)锂电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)电(dian)(dian)(dian)(dian)(dian)(dian)器供(gong)给LCD屏(ping)(ping)的(de)驱动，立异的(de)利(li)用(yong)(yong)(yong)4-位LCD显现屏(ping)(ping)为各(ge)类(lei)电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，主动区分极(ji)性的(de)，在充(chong)电(dian)(dian)(dian)(dian)(dian)(dian)时或(huo)不(bu)在充(chong)电(dian)(dian)(dian)(dian)(dian)(dian)时，显现电(dian)(dian)(dian)(dian)(🔴dian)(dian)池(chi)电(dian)(dian)(dian)(dian)(dian)(dian)量。SE9120能够或(huo)许(xu)利(li)用(yong)(yong)(yong)在全能充(chong)电(dian)(dian)(dian)(dian)(dian)(dian)器和USB充(chong)电(dian)(dian)(dian)(dian)(dian)(dian)器利(li)用(yong)(yong)(yong)LCD屏(ping)(ping)显现的(de)计划中。

      SE9120 是一个款用于显示電池板電池容量运行的模式级存储芯片。SE9120外部链接集变为了考虑源、秒表出现器、频度熬制政府部门，多边带动LED政府部门。SE9120可能或是检查测量電池板端电压的信息有时候可能或是带动四格柱型LCD显示出電池容量。

 SE9120测量锂电三根端的电流值，并根据锂电端的电流值，和转化了为为了响应的电容量类别，用四格柱型的LCD显著屏显著锂电电容量。锂电端的电流值显著接下来：      Vbat<3.7V，消耗的能量压低40%，LCD消失屏五个格全灭；

     3.7V

     3.8V

     3.9V

     Vbat >4.0V，正能量约为100%，LCD显现出屏七个格全亮；

右图一样，SE9120的采用用电线路图

SE9020C/D的首要特色:

●自动辨别干电池正负的作用与功效   ●内建20mA(TYP)蓝LED背光安装驱动 ●双向win7驱动下载手艺人win7驱动下载LCD触摸屏  

●嵌入正确的决定性电压降源    ●内建频率和次数调里部门，对区別手机充电第一阶段关闭程序频率和次数调里。    ●内建储电量显示测量政府部门，能也许突显電池储电量显示及手机充电进度计划    ●提供了SOP14和COB封装形式

 

包装、订价和供给  

思旺的SE9120接纳孩子SOP14和COB二极管封装。
