Maxim公司日前推出高頻、多化學類型電池充電器IC MAX17005/MAX17006/MAX17015。器件采用專有的(de)高頻電流模式(shi)架構，可(ke)顯(xian)著(zhu)降低(di)成(cheng)本和外部元件的(de)尺寸。

     該系列IC設計工作于1.2MHz高開關頻率，與許多其它電池充電器IC相比，允(yun)許使用尺寸(cun)更小的(de)輸出濾波(bo)(bo)器(qi)，從而(er)(er)降低(di)了輸出濾波(bo)(bo)器(qi)的(de)設(she)計(ji)尺寸(cun)和BOM成本(ben)。此外，該系列電池充電器(qi)IC允(yun)許使用n溝道功率(lv)選擇開關，而(er)(er)無需使用常規設(she)計(ji)中采用的(de)更為昂貴的(de)p溝道功率(lv)開關。

     MAX17005/MAX17006/MAX17015能夠(gou)節省(sheng)空間和成(cheng)本，理想用(yong)于筆記本電(dian)(dian)(dian)(dian)腦(nao)、臺式PC以及(ji)其它(ta)便攜式設(she)可再充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池。MAX17005可用(yong)于三(san)至(zhi)四節電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(單節電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)為4.2V至(zhi)4.4V)；MAX17006可用(yong)于兩至(zhi)三(san)節電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(單節電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)為4.2V至(zhi)4.4V)；MAX17015可通過輸(shu)出端的(de)(de)反饋(kui)電(dian)(dian)(dian)(dian)阻分壓(ya)器(qi)調節充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)(dian)池節數。此外，該系列器(qi)件(jian)可提供與適配(pei)器(qi)電(dian)(dian)(dian)(dian)流成(cheng)正比的(de)(de)高精(jing)度模擬輸(shu)出。在沒(mei)有(you)(you)連接適配(pei)器(qi)時(shi)，MAX17015的(de)(de)電(dian)(dian)(dian)(dian)流檢(jian)測(ce)電(dian)(dian)(dian)(dian)路依(yi)然保(bao)(bao)持有(you)(you)效，以監(jian)測(ce)電(dian)(dian)(dian)(dian)池的(de)(de)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流。所有(you)(you)器(qi)件(jian)均(jun)可采用(yong)20mΩ檢(jian)測(ce)電(dian)(dian)(dian)(dian)阻提供至(zhi)少4A的(de)(de)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，并具有(you)(you)過壓(ya)保(bao)(bao)護功(gong)能。

       MAX17005/MAX17006/MAX17015提(ti)供小型、4mm×4mm×0.8mm、20引腳(jiao)無鉛TQFN封裝，工(gong)作在-40°C至+85°C擴展工(gong)業級溫度(du)范圍。芯(xin)片起(qi)價為$5.66 (1000片起(qi)，美國離岸(an)價)。
