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(jian)(jian)采用專有的(de)(de)高頻電流模式架(jia)構，可(ke)顯著降低成本和(he)外部元件(jian)(jian)的(de)(de)尺(chi)寸(cun)。

     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，允許(xu)使用(yong)尺寸(cun)更小的輸出濾(lv)波器，從(cong)而(er)降低了(le)輸出濾(lv)波器的設計尺寸(cun)和(he)BOM成(cheng)本。此外(wai)，該系列電池充(chong)電器IC允許(xu)使用(yong)n溝道(dao)功(gong)率選擇開(kai)關(guan)，而(er)無需使用(yong)常規設計中采用(yong)的更為昂貴的p溝道(dao)功(gong)率開(kai)關(guan)。

     MAX17005/MAX17006/MAX17015能(neng)夠節省空間和成(cheng)本(ben)(ben)，理(li)想用(yong)(yong)于筆記本(ben)(ben)電(dian)(dian)(dian)腦(nao)、臺式(shi)PC以及其它便攜(xie)式(shi)設(she)可(ke)再充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)。MAX17005可(ke)用(yong)(yong)于三至四節電(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(單(dan)節電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)為(wei)4.2V至4.4V)；MAX17006可(ke)用(yong)(yong)于兩至三節電(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(單(dan)節電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)為(wei)4.2V至4.4V)；MAX17015可(ke)通過輸(shu)出(chu)端的反饋電(dian)(dian)(dian)阻分(fen)壓(ya)器調節充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)池(chi)節數。此外，該系列器件可(ke)提(ti)供(gong)與適(shi)配器電(dian)(dian)(dian)流(liu)(liu)成(cheng)正比的高(gao)精度(du)模(mo)擬輸(shu)出(chu)。在沒有(you)連接適(shi)配器時(shi)，MAX17015的電(dian)(dian)(dian)流(liu)(liu)檢(jian)測電(dian)(dian)(dian)路依然保(bao)持有(you)效(xiao)，以監測電(dian)(dian)(dian)池(chi)的放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)。所(suo)有(you)器件均可(ke)采用(yong)(yong)20mΩ檢(jian)測電(dian)(dian)(dian)阻提(ti)供(gong)至少4A的充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)，并具有(you)過壓(ya)保(bao)護功能(neng)。

       MAX17005/MAX17006/MAX17015提供小型、4mm×4mm×0.8mm、20引腳無鉛TQFN封裝，工(gong)作在-40°C至+85°C擴展工(gong)業(ye)級溫(wen)度范圍。芯片起(qi)價(jia)(jia)為$5.66 (1000片起(qi)，美國離岸(an)價(jia)(jia))。
