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)件采用專有的(de)高頻電(dian)流模式(shi)架構(gou)，可顯(xian)著降低成(cheng)本和外部元件的(de)尺寸(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相比(bi)，允許使(shi)用尺寸更(geng)(geng)小(xiao)的(de)(de)輸出(chu)濾波(bo)器，從而(er)(er)降低了輸出(chu)濾波(bo)器的(de)(de)設(she)計(ji)尺寸和BOM成本。此外，該系列電池充電器IC允許使(shi)用n溝(gou)道(dao)(dao)功率選擇開關，而(er)(er)無(wu)需(xu)使(shi)用常規設(she)計(ji)中采用的(de)(de)更(geng)(geng)為昂貴的(de)(de)p溝(gou)道(dao)(dao)功率開關。

     MAX17005/MAX17006/MAX17015能夠節(jie)省(sheng)空(kong)間和(he)成本，理想用于(yu)筆記本電(dian)(dian)(dian)(dian)腦(nao)、臺式PC以及其它便攜式設可(ke)再充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池。MAX17005可(ke)用于(yu)三至(zhi)(zhi)(zhi)四(si)節(jie)電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(單節(jie)電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)(ya)為4.2V至(zhi)(zhi)(zhi)4.4V)；MAX17006可(ke)用于(yu)兩(liang)至(zhi)(zhi)(zhi)三節(jie)電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(單節(jie)電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)(ya)為4.2V至(zhi)(zhi)(zhi)4.4V)；MAX17015可(ke)通過輸出(chu)端的(de)(de)反(fan)饋電(dian)(dian)(dian)(dian)阻分壓(ya)(ya)器調節(jie)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)(ya)和(he)電(dian)(dian)(dian)(dian)池節(jie)數。此外(wai)，該(gai)系列器件可(ke)提(ti)供(gong)(gong)與適(shi)(shi)配器電(dian)(dian)(dian)(dian)流成正比的(de)(de)高(gao)精度模擬(ni)輸出(chu)。在沒有連接適(shi)(shi)配器時(shi)，MAX17015的(de)(de)電(dian)(dian)(dian)(dian)流檢測電(dian)(dian)(dian)(dian)路(lu)依然(ran)保(bao)持有效，以監測電(dian)(dian)(dian)(dian)池的(de)(de)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流。所有器件均可(ke)采用20mΩ檢測電(dian)(dian)(dian)(dian)阻提(ti)供(gong)(gong)至(zhi)(zhi)(zhi)少4A的(de)(de)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，并具有過壓(ya)(ya)保(bao)護功能。

       MAX17005/MAX17006/MAX17015提(ti)供小型(xing)、4mm×4mm×0.8mm、20引(yin)腳無鉛TQFN封裝，工作在-40°C至+85°C擴(kuo)展工業(ye)級溫度(du)范圍(wei)。芯片(pian)(pian)起(qi)(qi)價(jia)為(wei)$5.66 (1000片(pian)(pian)起(qi)(qi)，美國離(li)岸價(jia))。
