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)件可在不改變(bian)外(wai)部(bu)(bu)元件的條件下通過(guo)SMBus接口對充(chong)電(dian)(dian)(dian)設(she)(she)置進行編(bian)程，大(da)大(da)提高了設(she)(she)計靈活性。可編(bian)程設(she)(she)置包(bao)括充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)、充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓、輸入(ru)限流(liu)(liu)、再學習電(dian)(dian)(dian)壓以及(ji)數字IINP電(dian)(dian)(dian)壓回(hui)讀。功能類(lei)似的競爭方(fang)案則需使用外(wai)部(bu)(bu)元件編(bian)程充(chong)電(dian)(dian)(dian)設(she)(she)置。MAX17435MAX17535可理想用于筆(bi)記(ji)本電(dian)(dian)(dian)腦(nao)、超便攜PC(UMPC)、移動互聯網設(she)(she)備(bei)(MID)及(ji)其它對空間(jian)尺(chi)寸要求嚴格(ge)的電(dian)(dian)(dian)池供(gong)電(dian)(dian)(dian)應(ying)用。

　　MAX17435MAX17535可(ke)提供±0.4%的電池電壓(ya)精度。低失調電流檢(jian)測放大器采用10mΩ檢(jian)流電阻提供±3%的充電電流精度。在接(jie)入適配器時，器件(jian)內部的電荷泵用于驅動適配器n溝道(dao)(dao)MOSFET;當(dang)適配器斷(duan)開時，通過p溝道(dao)(dao)MOSFET選(xuan)擇電池。

　　MAX17435MAX17535采用節(jie)省(sheng)空(kong)間的(de)4mmx4mm、24引(yin)腳(jiao)TQFN封裝，封裝背部(bu)帶有裸焊盤。器(qi)件(jian)工作在-40°C至(zhi)+85°C擴展級溫度范圍。可提供帶有推薦(jian)外部(bu)元件(jian)的(de)評估板，以(yi)加速設計進程。
