美蓓亞三美集團旗下三美電機，全新發布內置電池電壓監測端子的雙節電池用保護IC“MQC883系列”助力超快速充電！
美蓓亞三美集團旗下的三美電機（以下簡稱“三美電機”），推出的全新產品MQC883系列是用于智能手機和其他信息終端設備的鋰離子電池保護IC。
MQC883系列可以在美國高通的驍龍雙(shuang)芯移動平臺中(zhong)，與快速充電系統(tong)相輔相成。
近年來(lai)，隨著使用鋰(li)離子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的產品，特別是對于智能(neng)手機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)大(da)容量需求的日(ri)益增加(jia)。由于大(da)容量電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)需要(yao)較(jiao)長的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間，因(yin)此對能(neng)夠以(yi)大(da)功(gong)率(lv)快速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的系統的需求也在(zai)不(bu)斷增加(jia)。同(tong)時(shi)，在(zai)大(da)功(gong)率(lv)快速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，既要(yao)增加(jia)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，又(you)要(yao)減少產生的熱量，所以(yi)支(zhi)持大(da)功(gong)率(lv)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的雙(shuang)節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)和更高充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的機(ji)型(xing)越來(lai)越多(duo)。針對這些市場需求，美蓓亞三美開(kai)發了“MQC883系列”，通過(guo)在(zai)雙(shuang)節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)保護IC上增加(jia)一個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓監(jian)測(ce)端子，達到準確監(jian)測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，以(yi)補充(chong)(chong)(chong)(chong)雙(shuang)節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)剩(sheng)余電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量測(ce)量系統的性能(neng)。
特點
① 利用電池電壓監控端子精確監測電池電壓
→ 無法從電(dian)池(chi)組的(de)正負極監(jian)測(ce)(ce)單個電(dian)池(chi)電(dian)壓。通過(guo)使用電(dian)池(chi)保護(hu)IC的(de)BS端子，可以安全、準確(que)地(di)監(jian)測(ce)(ce)電(dian)池(chi)電(dian)壓，且不(bu)受感測(ce)(ce)電(dian)阻(zu)(zu)、MOSFET導通電(dian)阻(zu)(zu)和(he)接線電(dian)阻(zu)(zu)等電(dian)阻(zu)(zu)元件(jian)的(de)影響。
② 通過檢測電池和感應電阻器之間的電壓，防止電池組出現過充電/過放電/過電流等問題
→內(nei)置功能可在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)過程中(zhong)監(jian)測電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)，并在過充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)和(he)過放(fang)電(dian)(dian)(dian)(dian)(dian)時(shi)關閉(bi)充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)MOSFET以(yi)中(zhong)斷(duan)充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，還可監(jian)測感應電(dian)(dian)(dian)(dian)(dian)阻(zu)兩端的電(dian)(dian)(dian)(dian)(dian)壓(ya)，并在過電(dian)(dian)(dian)(dian)(dian)流時(shi)關閉(bi)充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)MOSFET以(yi)中(zhong)斷(duan)異常電(dian)(dian)(dian)(dian)(dian)流。
③ 監測電池組內部的溫度，在溫度異常升高時中斷充放電電流，以確保電池組的安全
→電池保護IC監測(ce)外部NTC熱(re)敏(min)電阻(zu)的阻(zu)值(zhi)變化(hua)，在阻(zu)值(zhi)變化(hua)到相當于異常高溫時(shi)，關閉(bi)充放(fang)電控(kong)制(zhi)MOSFET，切(qie)斷充放(fang)電電流。
主要用途
用于智能手(shou)機和其他(ta)設備(bei)的(de)鋰離(li)(li)子充電(dian)電(dian)池(chi)組和鋰離(li)(li)子聚合(he)物充電(dian)電(dian)池(chi)組。
