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(cai)用專有的高頻電流(liu)模式(shi)架構，可顯著降低(di)成本(ben)和外部元件的尺寸。

     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，允許使用尺寸(cun)更小的(de)輸出濾波(bo)器，從而降低(di)了(le)輸出濾波(bo)器的(de)設(she)計尺寸(cun)和BOM成本。此外，該系(xi)列電(dian)(dian)池充(chong)電(dian)(dian)器IC允許使用n溝(gou)道功率選擇開關，而無需使用常規(gui)設(she)計中采用的(de)更為昂貴的(de)p溝(gou)道功率開關。

     MAX17005/MAX17006/MAX17015能(neng)夠節省空間和成本(ben)，理想用于筆(bi)記本(ben)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)、臺式PC以及其它便攜式設可(ke)再充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。MAX17005可(ke)用于三(san)至(zhi)(zhi)四節電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(單(dan)節電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為4.2V至(zhi)(zhi)4.4V)；MAX17006可(ke)用于兩(liang)至(zhi)(zhi)三(san)節電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(單(dan)節電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為4.2V至(zhi)(zhi)4.4V)；MAX17015可(ke)通過(guo)(guo)輸(shu)出端的(de)反(fan)饋電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)分壓(ya)器調(diao)節充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)節數。此外，該系列器件可(ke)提(ti)供與適(shi)配(pei)器電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流成正比的(de)高精度模擬(ni)輸(shu)出。在沒(mei)有連(lian)接適(shi)配(pei)器時，MAX17015的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流檢測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路依然保持有效，以監測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流。所有器件均可(ke)采(cai)用20mΩ檢測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)提(ti)供至(zhi)(zhi)少4A的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，并具有過(guo)(guo)壓(ya)保護功(gong)能(neng)。

       MAX17005/MAX17006/MAX17015提(ti)供小型、4mm×4mm×0.8mm、20引腳無(wu)鉛TQFN封裝，工作在(zai)-40°C至+85°C擴(kuo)展工業級溫度范圍(wei)。芯片(pian)起價為$5.66 (1000片(pian)起，美國離岸(an)價)。
