Maxim推出分別工作在850kHz和500kHz的高度集成、SMBus電池充電器MAX17435MAX17535。器件(jian)可(ke)在不改變外部(bu)(bu)元(yuan)件(jian)的(de)條(tiao)件(jian)下通過SMBus接(jie)口對(dui)(dui)充(chong)(chong)電(dian)(dian)設置進行編(bian)程，大大提高(gao)了設計(ji)靈(ling)活性。可(ke)編(bian)程設置包(bao)括充(chong)(chong)電(dian)(dian)電(dian)(dian)流、充(chong)(chong)電(dian)(dian)電(dian)(dian)壓、輸入限流、再(zai)學習電(dian)(dian)壓以及數字IINP電(dian)(dian)壓回讀。功(gong)能類似的(de)競爭方案則需使用外部(bu)(bu)元(yuan)件(jian)編(bian)程充(chong)(chong)電(dian)(dian)設置。MAX17435MAX17535可(ke)理想(xiang)用于筆記本電(dian)(dian)腦(nao)、超(chao)便攜PC(UMPC)、移動互聯網設備(MID)及其它(ta)對(dui)(dui)空間(jian)尺寸要求(qiu)嚴格(ge)的(de)電(dian)(dian)池供電(dian)(dian)應用。

　　MAX17435MAX17535可提供±0.4%的電(dian)(dian)池電(dian)(dian)壓精度(du)。低失調(diao)電(dian)(dian)流檢測放大(da)器(qi)(qi)采用10mΩ檢流電(dian)(dian)阻提供±3%的充(chong)電(dian)(dian)電(dian)(dian)流精度(du)。在接入適(shi)配(pei)器(qi)(qi)時(shi)，器(qi)(qi)件內部(bu)的電(dian)(dian)荷泵(beng)用于驅動適(shi)配(pei)器(qi)(qi)n溝(gou)道(dao)MOSFET;當(dang)適(shi)配(pei)器(qi)(qi)斷開(kai)時(shi)，通過p溝(gou)道(dao)MOSFET選擇電(dian)(dian)池。

　　MAX17435MAX17535采用節省空間的4mmx4mm、24引腳TQFN封(feng)裝，封(feng)裝背部(bu)帶(dai)有(you)裸焊盤。器件工作在-40°C至+85°C擴展級溫度范圍。可(ke)提供(gong)帶(dai)有(you)推薦外部(bu)元件的評估板，以(yi)加速設計進程。
