Maxim推出分別工作在850kHz和500kHz的高度集成、SMBus電池充電器MAX17435MAX17535。器(qi)件(jian)(jian)可在不改變外(wai)(wai)部(bu)元件(jian)(jian)的(de)條件(jian)(jian)下通過SMBus接口對充電(dian)(dian)(dian)設(she)置進行編(bian)程，大大提高了設(she)計(ji)靈活性。可編(bian)程設(she)置包括充電(dian)(dian)(dian)電(dian)(dian)(dian)流、充電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)、輸(shu)入限流、再學習電(dian)(dian)(dian)壓(ya)以及數字IINP電(dian)(dian)(dian)壓(ya)回讀(du)。功能類(lei)似(si)的(de)競爭(zheng)方案(an)則(ze)需使用(yong)外(wai)(wai)部(bu)元件(jian)(jian)編(bian)程充電(dian)(dian)(dian)設(she)置。MAX17435MAX17535可理(li)想用(yong)于筆記本電(dian)(dian)(dian)腦、超便攜PC(UMPC)、移(yi)動互聯(lian)網設(she)備(MID)及其它(ta)對空間尺(chi)寸要(yao)求嚴格的(de)電(dian)(dian)(dian)池(chi)供(gong)電(dian)(dian)(dian)應用(yong)。

　　MAX17435MAX17535可提(ti)供(gong)±0.4%的電(dian)池電(dian)壓精(jing)度(du)(du)。低失調電(dian)流檢(jian)測(ce)放(fang)大器采(cai)用(yong)10mΩ檢(jian)流電(dian)阻提(ti)供(gong)±3%的充電(dian)電(dian)流精(jing)度(du)(du)。在接入適(shi)配器時，器件內部(bu)的電(dian)荷泵用(yong)于驅(qu)動(dong)適(shi)配器n溝道MOSFET;當適(shi)配器斷開時，通過p溝道MOSFET選擇電(dian)池。

　　MAX17435MAX17535采用節省空間的4mmx4mm、24引腳TQFN封裝，封裝背部帶有裸焊盤。器件工作在-40°C至+85°C擴展(zhan)級溫度(du)范圍。可提(ti)供帶有推薦外(wai)部元(yuan)件的評估板，以加(jia)速設計進程。
