闡述：

CN3303都是款任務卡于2.75V到6.5V的PFM升壓型三節鋰鋰電快充放肆一體化集成運放。 CN3303得到恒流和準恒壓形勢(Quasi-CV^TM)對進行充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)板關閉程序進行充(chong)電(dian)(dian)(dian)(dian)申領，外表模塊化有基準點電(dian)(dian)(dian)(dian)阻值源，電(dian)(dian)(dian)(dian)感(gan)額定電(dian)(dian)(dian)(dian)壓檢側工具基層單(dan)位(wei)，進行充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)板電(dian)(dian)(dian)(dian)阻值檢側工具電(dian)(dian)(dian)(dian)源線路(lu)和(he)片外場效果單(dan)晶體管(guan)驅動包(bao)電(dian)(dian)(dian)(dian)源線路(lu)等(deng)(deng)，兼具外表pcb板少，電(dian)(dian)(dian)(dian)源線路(lu)容易(yi)等(deng)(deng)特點。

當(dang)(dang)接起(qi)所在主機(ji)電(dian)(dian)(dian)(dian)(dian)源后，CN3303進去(qu)沖(chong)電(dian)(dian)(dian)(dian)(dian)現(xian)(xian)狀，有節制片外(wai)N溝(gou)(gou)道MOSFET導通，電(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)電(dian)(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)(dian)流值回落，當(dang)(dang)回落到(dao)(dao)表(biao)面電(dian)(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)(dian)流值檢查(cha)(cha)測量(liang)電(dian)(dian)(dian)(dian)(dian)阻(zu)器安裝的(de)累計(ji)時，片外(wai)N溝(gou)(gou)道MOSFET停(ting)止工(gong)作，電(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)感(gan)(gan)(gan)應直(zhi)流電(dian)(dian)(dian)(dian)(dian)壓下降(jiang)，電(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)中的(de)正能(neng)(neng)量(liang)轉變到(dao)(dao)鋰(li)電(dian)(dian)(dian)(dian)(dian)池中。當(dang)(dang)電(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)感(gan)(gan)(gan)應直(zhi)流電(dian)(dian)(dian)(dian)(dian)壓下降(jiang)到(dao)(dao)對(dui)外(wai)部(bu)感(gan)(gan)(gan)應直(zhi)流電(dian)(dian)(dian)(dian)(dian)壓查(cha)(cha)測功率電(dian)(dian)(dian)(dian)(dian)阻(zu)布置的(de)累計(ji)時，片外(wai)N溝(gou)(gou)道MOSFET再(zai)導通，如斯天道輪回。當(dang)(dang)BAT管腳(jiao)(jiao)端電(dian)(dian)(dian)(dian)(dian)壓第一名(ming)次達到(dao)(dao)外(wai)表(biao)快速設置的(de)12.6V(經典故事(shi)值)時，CN3303滲入準恒(heng)(heng)壓快充(chong)事(shi)態，以較小電(dian)(dian)(dian)(dian)(dian)壓對(dui)電(dian)(dian)(dian)(dian)(dian)池蓄電(dian)(dian)(dian)(dian)(dian)快充(chong)。在準恒(heng)(heng)壓事(shi)態，當(dang)(dang)BAT管腳(jiao)(jiao)額定電(dian)(dian)(dian)(dian)(dian)壓抵達12.6V時，蓄電(dian)(dian)(dian)(dian)(dian)程序竣事(shi)，片外(wai)N溝(gou)(gou)道MOSFET堅定不移停(ting)機(ji)現(xian)(xian)況(kuang)。當(dang)(dang)BAT管腳(jiao)(jiao)電(dian)(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)(dian)流降(jiang)低到(dao)(dao)再(zai)充(chong)點(dian)閥值時，CN3303最后來(lai)到(dao)(dao)快充(chong)請況(kuang)。CN3303最低世界任務頻(pin)率能(neng)(neng)達1MHz。

當鋰電電流(liu)相(xiang)電壓(ya)超過(guo)讀取電流(liu)相(xiang)電壓(ya)或鋰電短路(lu)等問題時(shi)，CN3303在片(pian)外N溝道(dao)MOSFET和P溝道(dao)MOSFET的(de)搞好團(tuan)結(jie)影(ying)響下，用(yong)較小電壓(ya)保持對電板能充電，對電板做到保護影(ying)響。

此外藥用價值涵蓋單片(pian)(pian)機芯片(pian)(pian)使能(neng)內(nei)容打出(chu)，管芯過溫保(bao)護和的情況唆使內(nei)容打出(chu)端等。

CN3303悅納自己8管腳的SOP8打包(bao)封裝。
