北京2015年5月15日電(dian)(dian)(dian)(dian) /美通社(she)/ -- 近日，德州(zhou)儀器(qi)(qi) (TI)推出了(le)業內首款采(cai)用(yong)專有(you)MaxCharge技術的(de)(de)全(quan)集成5A單節鋰離(li)子 (Li-ion) 電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)路(lu)。與現有(you)電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)相比，這(zhe)款器(qi)(qi)件將充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)間(jian)減(jian)少了(le)一半以上，較高可將充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)間(jian)減(jian)少60%，這(zhe)讓(rang)用(yong)戶(hu)可以實(shi)現快(kuai)速充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)同時(shi)(shi)又(you)不會受到發熱過量(liang)(liang)的(de)(de)困擾。開關(guan)模式充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)在較大限度地保持(chi)行(xing)業較快(kuai)速充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)間(jian)所具有(you)的(de)(de)優勢的(de)(de)同時(shi)(shi)，為(wei)用(yong)戶(hu)提(ti)供更加(jia)安全(quan)的(de)(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)體驗。為(wei)了(le)提(ti)升(sheng)用(yong)戶(hu)體驗，并(bing)延長眾多鋰離(li)子應用(yong)中電(dian)(dian)(dian)(dian)子元器(qi)(qi)件的(de)(de)使用(yong)壽(shou)命，MaxCharge技術縮短了(le)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)間(jian)并(bing)減(jian)少了(le)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)產生的(de)(de)熱量(liang)(liang)，這(zhe)些應用(yong)包括智能手機(ji)、平板電(dian)(dian)(dian)(dian)腦、無人機(ji)、移(yi)動(dong)電(dian)(dian)(dian)(dian)源(yuan)以及工(gong)業和醫療設備。

通過將窄幅電壓DC/DC電源路徑管理與TI此次推出的MaxCharge技術組合在一起，在電流達到3.5A時，溫度最少僅上升18攝氏度，可輕松(song)實(shi)現(xian)快速、低發熱(re)量充電(dian)(dian)，并在充電(dian)(dian)電(dian)(dian)流高達(da)5A的時支持高達(da)14V的輸入電(dian)(dian)壓(ya)。

特點和優勢：

• 通過支持高輸入電壓實現較快速的充電：業內首款支持5A充電電流和高達14V輸入電壓的單節鋰離子電池充電器。
• 較高效率：在輸入電壓 (Vin) 為9V，電流為3.5A時的充電效率高達91%，溫度僅上升18攝氏度。
• 更安全充電：設計人員通過控制IC溫度并使用熱調節環路優化熱性能來減少過多散熱。
• 高電池補充電流：充電器能夠為即時系統功率突發提供峰值9A的放電電流。
• 簡單設計集成：與TI的系列產品引腳到引腳兼容。

這款快速充電(dian)(dian)器(qi)設(she)計(ji)(ji)用于在具有(you)TI電(dian)(dian)池電(dian)(dian)量(liang)計(ji)(ji)的(de)(de)單節便(bian)攜式設(she)備中工作。例(li)如，將設(she)備與電(dian)(dian)池電(dian)(dian)量(liang)計(ji)(ji)技術進行配對，以確(que)保便(bian)攜式電(dian)(dian)子產品中更長的(de)(de)電(dian)(dian)池使用壽(shou)命和更加安(an)全的(de)(de)充電(dian)(dian)。

工具和支持

受I²C控制的(de)，1S，5A快速充電(dian)器是(shi)全新TI Designs參考設計中的(de)一款特(te)性化產品，，它(ta)采(cai)用面向高輸入電(dian)壓和可調(diao)USB OTG升壓的(de)MaxCharge技術，這(zhe)項技術能夠上(shang)手即用，以減少電(dian)池充電(dian)時間并在放電(dian)階(jie)段(duan)提升電(dian)池運行(xing)時間。

供貨情況

充電器已(yi)量產(chan)，并可(ke)通過(guo)TI Store和TI授權的分銷(xiao)商(shang)網絡購買。產(chan)品采(cai)用4mm x 4mm，24引腳四方扁(bian)平無引線 (QFN) 封裝。用于智能手機和平板(ban)電腦的和，此外，TI推(tui)出這款(kuan)全(quan)新的，此器件支持移動電源(yuan)。
