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)可(ke)在不改變(bian)外部(bu)元件(jian)的(de)條件(jian)下通過SMBus接口對(dui)充電(dian)(dian)(dian)設置進行編程(cheng)，大(da)大(da)提高了設計靈活性。可(ke)編程(cheng)設置包(bao)括充電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)、充電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)、輸入限(xian)流(liu)、再(zai)學(xue)習(xi)電(dian)(dian)(dian)壓(ya)以及數字IINP電(dian)(dian)(dian)壓(ya)回讀。功能類似的(de)競(jing)爭方案則需使用外部(bu)元件(jian)編程(cheng)充電(dian)(dian)(dian)設置。MAX17435MAX17535可(ke)理想用于(yu)筆記本電(dian)(dian)(dian)腦、超(chao)便攜(xie)PC(UMPC)、移(yi)動互聯網設備(MID)及其它對(dui)空(kong)間尺寸要求嚴(yan)格(ge)的(de)電(dian)(dian)(dian)池供(gong)電(dian)(dian)(dian)應用。

　　MAX17435MAX17535可提供±0.4%的(de)(de)電(dian)池電(dian)壓精度。低失調(diao)電(dian)流(liu)檢(jian)測放大器采用(yong)10mΩ檢(jian)流(liu)電(dian)阻提供±3%的(de)(de)充電(dian)電(dian)流(liu)精度。在接入適配(pei)器時(shi)(shi)，器件內部(bu)的(de)(de)電(dian)荷泵用(yong)于驅動(dong)適配(pei)器n溝(gou)道(dao)MOSFET;當適配(pei)器斷開時(shi)(shi)，通(tong)過p溝(gou)道(dao)MOSFET選擇電(dian)池。

　　MAX17435MAX17535采用(yong)節(jie)省空間的4mmx4mm、24引腳TQFN封裝，封裝背部帶(dai)有裸(luo)焊盤(pan)。器件(jian)工作在-40°C至(zhi)+85°C擴(kuo)展級溫度(du)范圍。可(ke)提供(gong)帶(dai)有推薦外部元件(jian)的評估板，以加速設計進程。
