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(de)高頻(pin)電(dian)流模(mo)式架構，可顯著降低成本和外(wai)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(xiang)比，允(yun)(yun)許(xu)使(shi)用(yong)尺(chi)寸(cun)更(geng)小的輸出濾波器，從而(er)降低了輸出濾波器的設計尺(chi)寸(cun)和BOM成本。此(ci)外，該(gai)系列電(dian)池(chi)充(chong)電(dian)器IC允(yun)(yun)許(xu)使(shi)用(yong)n溝道功率選擇開關(guan)，而(er)無需使(shi)用(yong)常規設計中采用(yong)的更(geng)為昂貴的p溝道功率開關(guan)。

     MAX17005/MAX17006/MAX17015能夠節(jie)省(sheng)空(kong)間和成本，理想用于(yu)筆記本電(dian)(dian)(dian)(dian)(dian)腦、臺式PC以及(ji)其它(ta)便攜式設可(ke)(ke)再充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池。MAX17005可(ke)(ke)用于(yu)三(san)至(zhi)四節(jie)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(單節(jie)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)4.2V至(zhi)4.4V)；MAX17006可(ke)(ke)用于(yu)兩至(zhi)三(san)節(jie)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(單節(jie)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)4.2V至(zhi)4.4V)；MAX17015可(ke)(ke)通(tong)過(guo)輸(shu)出端的(de)反饋電(dian)(dian)(dian)(dian)(dian)阻(zu)分壓(ya)器(qi)調(diao)節(jie)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)(dian)(dian)池節(jie)數。此外(wai)，該(gai)系列器(qi)件(jian)可(ke)(ke)提供(gong)與適配器(qi)電(dian)(dian)(dian)(dian)(dian)流成正比的(de)高精度模(mo)擬(ni)輸(shu)出。在(zai)沒有(you)連(lian)接適配器(qi)時，MAX17015的(de)電(dian)(dian)(dian)(dian)(dian)流檢(jian)(jian)測電(dian)(dian)(dian)(dian)(dian)路依然保(bao)持有(you)效(xiao)，以監測電(dian)(dian)(dian)(dian)(dian)池的(de)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流。所有(you)器(qi)件(jian)均可(ke)(ke)采用20mΩ檢(jian)(jian)測電(dian)(dian)(dian)(dian)(dian)阻(zu)提供(gong)至(zhi)少4A的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，并(bing)具有(you)過(guo)壓(ya)保(bao)護功(gong)能。

       MAX17005/MAX17006/MAX17015提供小型、4mm×4mm×0.8mm、20引腳(jiao)無鉛TQFN封裝(zhuang)，工作在-40°C至+85°C擴展工業(ye)級溫(wen)度范圍。芯片起(qi)價(jia)為$5.66 (1000片起(qi)，美國(guo)離岸價(jia))。
