Maxim公司日前推出高頻、多化學類型電池充電器IC MAX17005/MAX17006/MAX17015。器件采用專有的高(gao)頻電流模式架構，可顯著(zhu)降低(di)成本和外(wai)部(bu)元件的尺(chi)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(bi)，允(yun)許(xu)使用(yong)尺寸(cun)更小(xiao)的(de)輸出(chu)濾波器，從而(er)降低了輸出(chu)濾波器的(de)設計尺寸(cun)和BOM成本。此(ci)外，該系列電池充電器IC允(yun)許(xu)使用(yong)n溝道功(gong)率選(xuan)擇開關，而(er)無需使用(yong)常規設計中采用(yong)的(de)更為昂貴的(de)p溝道功(gong)率開關。

     MAX17005/MAX17006/MAX17015能(neng)夠節省空間和成(cheng)本，理想用(yong)于筆記(ji)本電(dian)(dian)(dian)(dian)(dian)(dian)腦、臺式PC以及其它便攜式設可(ke)再充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。MAX17005可(ke)用(yong)于三(san)至四節電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(單節電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)4.2V至4.4V)；MAX17006可(ke)用(yong)于兩至三(san)節電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(單節電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)4.2V至4.4V)；MAX17015可(ke)通過輸(shu)(shu)出(chu)端的(de)(de)(de)反饋電(dian)(dian)(dian)(dian)(dian)(dian)阻分壓(ya)器(qi)(qi)(qi)調節充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)節數。此外(wai)，該系(xi)列器(qi)(qi)(qi)件可(ke)提(ti)(ti)供與適(shi)配器(qi)(qi)(qi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)成(cheng)正比(bi)的(de)(de)(de)高精度模擬(ni)輸(shu)(shu)出(chu)。在沒有(you)連接(jie)適(shi)配器(qi)(qi)(qi)時(shi)，MAX17015的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)檢(jian)測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)路依然保持有(you)效，以監(jian)測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。所有(you)器(qi)(qi)(qi)件均(jun)可(ke)采用(yong)20mΩ檢(jian)測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)阻提(ti)(ti)供至少(shao)4A的(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，并具有(you)過壓(ya)保護功能(neng)。

       MAX17005/MAX17006/MAX17015提供小型、4mm×4mm×0.8mm、20引(yin)腳無(wu)鉛TQFN封裝，工作在-40°C至(zhi)+85°C擴展工業級溫度范圍。芯片起價(jia)為(wei)$5.66 (1000片起，美國離岸價(jia))。
