Maxim推出分別工作在850kHz和500kHz的高度集成、SMBus電池充電器MAX17435MAX17535。器件可在不改變外部元(yuan)(yuan)件的條件下通(tong)過SMBus接(jie)口對(dui)(dui)充(chong)電(dian)(dian)(dian)設(she)(she)(she)置(zhi)進行(xing)編(bian)程(cheng)，大大提(ti)高了(le)設(she)(she)(she)計靈活性(xing)。可編(bian)程(cheng)設(she)(she)(she)置(zhi)包括(kuo)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流、充(chong)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(shu)字IINP電(dian)(dian)(dian)壓(ya)回(hui)讀。功能類似的競爭方案(an)則(ze)需使(shi)用(yong)外部元(yuan)(yuan)件編(bian)程(cheng)充(chong)電(dian)(dian)(dian)設(she)(she)(she)置(zhi)。MAX17435MAX17535可理想用(yong)于筆記本電(dian)(dian)(dian)腦、超便攜PC(UMPC)、移動互聯(lian)網設(she)(she)(she)備(MID)及其它對(dui)(dui)空間尺寸(cun)要(yao)求嚴(yan)格的電(dian)(dian)(dian)池供電(dian)(dian)(dian)應(ying)用(yong)。

　　MAX17435MAX17535可提供±0.4%的電池電壓(ya)精度。低失調電流檢測放(fang)大器(qi)采用10mΩ檢流電阻提供±3%的充電電流精度。在接(jie)入適(shi)配(pei)(pei)器(qi)時，器(qi)件(jian)內部的電荷(he)泵用于驅動適(shi)配(pei)(pei)器(qi)n溝道(dao)MOSFET;當適(shi)配(pei)(pei)器(qi)斷開時，通過p溝道(dao)MOSFET選擇(ze)電池。

　　MAX17435MAX17535采用節省(sheng)空(kong)間的4mmx4mm、24引腳TQFN封裝，封裝背部帶有(you)裸焊盤(pan)。器(qi)件工作在-40°C至+85°C擴展級(ji)溫度(du)范圍(wei)。可提供(gong)帶有(you)推薦外部元件的評估板，以加速設計進程。
