diodes推出apm860x鋰電池充電器ic具備一系(xi)列安全功能，可為小型便攜式產(chan)品的充電過(guo)程提供保護。

　　單通道apm8600和雙通道apm8601能夠持續監控鋰離子和鋰聚合物電(dian)(dian)池的充(chong)電(dian)(dian)過(guo)程(cheng)(cheng)，避免(mian)出現過(guo)壓、充(chong)電(dian)(dian)時間過(guo)長或過(guo)溫情況，確(que)保手(shou)機、媒體(ti)播放(fang)器及耳機等產品的充(chong)電(dian)(dian)過(guo)程(cheng)(cheng)安(an)全(quan)可靠。

　　新器(qi)件提供高達28v的過壓(ya)保護(hu)，其中(zhong)apm8601能(neng)自動選擇usb或直流(liu)輸入，apm8600則為直流(liu)輸入唯一的器(qi)件。

　　這些集成電路的充電算法涵蓋所有鋰電池的(de)充(chong)電(dian)(dian)(dian)(dian)階段，包(bao)括為耗盡電(dian)(dian)(dian)(dian)量電(dian)(dian)(dian)(dian)池(chi)的(de)預充(chong)電(dian)(dian)(dian)(dian)、恒流或恒壓快速充(chong)電(dian)(dian)(dian)(dian)及充(chong)滿(top-off)充(chong)電(dian)(dian)(dian)(dian)，以保持電(dian)(dian)(dian)(dian)池(chi)在其充(chong)滿電(dian)(dian)(dian)(dian)的(de)水平(ping)。

　　apm86系列器件可通過外(wai)部(bu)元件選擇(ze)進行完(wan)全編程。充電(dian)(dian)電(dian)(dian)流、預(yu)充電(dian)(dian)及終止充電(dian)(dian)等均取決于(yu)電(dian)(dian)阻(zu)(zu)值和電(dian)(dian)容值的(de)充電(dian)(dian)時間。電(dian)(dian)池附近(jin)的(de)標準熱敏電(dian)(dian)阻(zu)(zu)可實現電(dian)(dian)池溫(wen)度(du)測量。器件的(de)充電(dian)(dian)指示(shi)燈引腳可顯示(shi)充電(dian)(dian)狀(zhuang)態。
