Maxim公司日前推出高頻、多化學類型電池充電器IC MAX17005/MAX17006/MAX17015。器件采用(yong)專有的高頻電流模式架構，可顯著降低(di)成(cheng)本(ben)和外部元(yuan)件的尺寸(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，允(yun)許使(shi)用尺寸(cun)更小的(de)(de)輸(shu)出濾(lv)波(bo)器，從(cong)而降低了輸(shu)出濾(lv)波(bo)器的(de)(de)設計(ji)尺寸(cun)和BOM成(cheng)本。此(ci)外(wai)，該系列電(dian)池充電(dian)器IC允(yun)許使(shi)用n溝道功(gong)率選擇(ze)開關(guan)(guan)，而無需使(shi)用常規(gui)設計(ji)中采用的(de)(de)更為昂貴的(de)(de)p溝道功(gong)率開關(guan)(guan)。

     MAX17005/MAX17006/MAX17015能夠節(jie)省空(kong)間和成本(ben)，理想用(yong)于(yu)筆記本(ben)電(dian)(dian)(dian)(dian)(dian)腦、臺式PC以及其它(ta)便(bian)攜式設可再充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。MAX17005可用(yong)于(yu)三(san)至(zhi)四節(jie)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(單節(jie)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓為4.2V至(zhi)4.4V)；MAX17006可用(yong)于(yu)兩至(zhi)三(san)節(jie)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(單節(jie)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓為4.2V至(zhi)4.4V)；MAX17015可通過(guo)輸出(chu)端的(de)反饋電(dian)(dian)(dian)(dian)(dian)阻分壓器(qi)(qi)調(diao)節(jie)充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)節(jie)數。此外，該系列器(qi)(qi)件可提(ti)供(gong)與適配器(qi)(qi)電(dian)(dian)(dian)(dian)(dian)流成正比的(de)高精度模擬輸出(chu)。在沒有連接適配器(qi)(qi)時，MAX17015的(de)電(dian)(dian)(dian)(dian)(dian)流檢測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)路依(yi)然保(bao)持(chi)有效，以監測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流。所(suo)有器(qi)(qi)件均(jun)可采用(yong)20mΩ檢測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)阻提(ti)供(gong)至(zhi)少4A的(de)充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，并具(ju)有過(guo)壓保(bao)護(hu)功(gong)能。

     ;  MAX17005/MAX17006/MAX17015提供小(xiao)型(xing)、4mm×4mm×0.8mm、20引(yin)腳(jiao)無鉛TQFN封裝，工作在-40°C至+85°C擴展(zhan)工業級溫度(du)范圍。芯片(pian)起價(jia)為(wei)$5.66 (1000片(pian)起，美(mei)國離岸價(jia))。
