充電器芯在片20世紀80年代首次推出，它簡化了NiCd和NiMH充電器的設計，因為這些化學品的電池難以充電。鋰離子電池更簡(jian)單，大(da)(da)多數現代充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)片(pian)還(huan)包(bao)括安全充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)鋰離子電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)所需的(de)保護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)路。還(huan)有(you)(you)些(xie)包(bao)括電(dian)(dian)(dian)(dian)(dian)(dian)流和電(dian)(dian)(dian)(dian)(dian)(dian)壓調節，FET開關(guan)，有(you)(you)些(xie)還(huan)包(bao)含(han)電(dian)(dian)(dian)(dian)(dian)(dian)荷狀(zhuang)態指(zhi)示(shi)和電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)平(ping)衡(heng)。添加到大(da)(da)多數芯(xin)片(pian)的(de)是(shi)超時(shi)定時(shi)器，如(ru)果在為有(you)(you)缺陷的(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)沒有(you)(you)按預(yu)期發生(sheng)可預(yu)測的(de)癥狀(zhuang)，則(ze)停止(zhi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。先進的(de)芯(xin)片(pian)還(huan)具有(you)(you)預(yu)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)調節功能(neng)（增強(qiang)）喚醒不活(huo)動的(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，以及在電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)存放(fang)時(shi)降低電(dian)(dian)(dian)(dian)(dian)(dian)路管理電(dian)(dian)(dian)(dian)(dian)(dian)流的(de)睡眠模式(shi)。如(ru)果寄生(sheng)負載在駐留在充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器中時(shi)將電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓降低到預(yu)設(she)閾值以下，則(ze)某(mou)些(xie)芯(xin)片(pian)也會啟動充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。

盡管(guan)充(chong)(chong)(chong)電(dian)(dian)(dian)器芯(xin)(xin)(xin)片(pian)(pian)(pian)使用(yong)(yong)簡(jian)單(dan)且經濟，但它(ta)們具有局(ju)限(xian)性。大(da)多數(shu)提供固定費(fei)用(yong)(yong)算法(fa)，不(bu)允許(xu)對特(te)殊(shu)用(yong)(yong)途(tu)進行微調。芯(xin)(xin)(xin)片(pian)(pian)(pian)是針對給(gei)定電(dian)(dian)(dian)池制造的(de)(de)，并(bing)且可能無法(fa)滿足用(yong)(yong)戶要(yao)求的(de)(de)不(bu)同化學成分或讀(du)取(qu)可嵌入電(dian)(dian)(dian)池座中的(de)(de)電(dian)(dian)(dian)池代碼(ma)。當(dang)對老化電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)時，大(da)多數(shu)芯(xin)(xin)(xin)片(pian)(pian)(pian)也不(bu)會調整到最佳充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)。微控制器提供充(chong)(chong)(chong)電(dian)(dian)(dian)器芯(xin)(xin)(xin)片(pian)(pian)(pian)的(de)(de)替代品。雖然由(you)于需要(yao)額外的(de)(de)編程時間，設計成本(ben)(ben)(ben)更高，但制造成本(ben)(ben)(ben)與充(chong)(chong)(chong)電(dian)(dian)(dian)器芯(xin)(xin)(xin)片(pian)(pian)(pian)兼容。我們要(yao)注意(yi)，充(chong)(chong)(chong)電(dian)(dian)(dian)芯(xin)(xin)(xin)片(pian)(pian)(pian)或微控制器僅形成充(chong)(chong)(chong)電(dian)(dian)(dian)器電(dian)(dian)(dian)路(lu)的(de)(de)一小(xiao)部分; 大(da)部分成本(ben)(ben)(ben)在于外圍組件，包括固態開關(guan)，信號燈和電(dian)(dian)(dian)源(yuan)。零件成本(ben)(ben)(ben)與瓦數(shu)直接相關(guan)。

可(ke)提供工廠配置的(de)充電(dian)(dian)(dian)器模(mo)塊，其設置為正確的(de)電(dian)(dian)(dian)壓(ya)，電(dian)(dian)(dian)流和(he)算(suan)法。有(you)些具有(you)無縫DC-DC轉換(huan)功能(neng)，可(ke)以(yi)為電(dian)(dian)(dian)池充電(dian)(dian)(dian)，其電(dian)(dian)(dian)壓(ya)高(gao)于輸入電(dian)(dian)(dian)壓(ya)。選項包括SMBus，太陽能(neng)充電(dian)(dian)(dian)，校準和(he)顯示放電(dian)(dian)(dian)。使用軟可(ke)編程(cheng)充電(dian)(dian)(dian)器模(mo)塊類(lei)似于現成的(de)交流電(dian)(dian)(dian)源，這種(zhong)電(dian)(dian)(dian)源在20世(shi)紀90年代(dai)開始(shi)流行(xing)，作為為每種(zhong)應用構建自己的(de)充電(dian)(dian)(dian)器的(de)低成本替代(dai)方案(an)。
