Maxim公司日前推出高頻、多化學類型電池充電器IC MAX17005/MAX17006/MAX17015。器(qi)件采用(yong)專有的(de)高頻電流模式架構(gou)，可(ke)顯著降低成本(ben)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，允許使(shi)用尺(chi)寸更(geng)小的(de)輸出(chu)濾波(bo)器(qi)(qi)，從而(er)降低了輸出(chu)濾波(bo)器(qi)(qi)的(de)設計(ji)尺(chi)寸和(he)BOM成本。此(ci)外(wai)，該系列電池(chi)充電器(qi)(qi)IC允許使(shi)用n溝道(dao)功(gong)率選擇開關(guan)，而(er)無需使(shi)用常(chang)規設計(ji)中采用的(de)更(geng)為昂(ang)貴的(de)p溝道(dao)功(gong)率開關(guan)。

     MAX17005/MAX17006/MAX17015能(neng)夠(gou)節(jie)省空間和成本(ben)，理想用于(yu)筆記本(ben)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦、臺(tai)式PC以及其它便攜(xie)式設可(ke)再充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池。MAX17005可(ke)用于(yu)三至四節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(單(dan)節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)4.2V至4.4V)；MAX17006可(ke)用于(yu)兩至三節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(單(dan)節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)4.2V至4.4V)；MAX17015可(ke)通過輸(shu)出(chu)端的反饋(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻分(fen)壓(ya)器調節(jie)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池節(jie)數。此(ci)外(wai)，該系列器件可(ke)提供(gong)與適配(pei)器電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)成正(zheng)比的高精(jing)度模擬輸(shu)出(chu)。在(zai)沒(mei)有(you)連(lian)接適配(pei)器時，MAX17015的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)檢測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路依(yi)然保持有(you)效，以監測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。所有(you)器件均可(ke)采用20mΩ檢測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻提供(gong)至少4A的充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，并具(ju)有(you)過壓(ya)保護功能(neng)。

       MAX17005/MAX17006/MAX17015提供小(xiao)型、4mm×4mm×0.8mm、20引腳(jiao)無鉛TQFN封(feng)裝(zhuang)，工作在-40°C至+85°C擴展工業級溫(wen)度范圍。芯片起價為$5.66 (1000片起，美國離岸價)。
