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)可在不改變外部元件(jian)的(de)條(tiao)件(jian)下通過SMBus接口對(dui)充電(dian)(dian)(dian)設(she)置(zhi)進行編(bian)程，大大提高了設(she)計靈活性。可編(bian)程設(she)置(zhi)包括充電(dian)(dian)(dian)電(dian)(dian)(dian)流、充電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)、輸入(ru)限流、再學(xue)習電(dian)(dian)(dian)壓(ya)以(yi)及(ji)數字IINP電(dian)(dian)(dian)壓(ya)回讀。功能類(lei)似的(de)競爭方案則(ze)需(xu)使用外部元件(jian)編(bian)程充電(dian)(dian)(dian)設(she)置(zhi)。MAX17435MAX17535可理(li)想用于筆(bi)記本電(dian)(dian)(dian)腦、超便攜PC(UMPC)、移動互(hu)聯(lian)網設(she)備(MID)及(ji)其它對(dui)空間(jian)尺寸要求嚴格的(de)電(dian)(dian)(dian)池供電(dian)(dian)(dian)應用。

　　MAX17435MAX17535可提(ti)供±0.4%的電(dian)池電(dian)壓(ya)精(jing)度。低失調(diao)電(dian)流檢測放大器采用10mΩ檢流電(dian)阻提(ti)供±3%的充電(dian)電(dian)流精(jing)度。在接入適配(pei)器時(shi)(shi)，器件內(nei)部的電(dian)荷泵用于(yu)驅(qu)動適配(pei)器n溝(gou)(gou)道MOSFET;當適配(pei)器斷(duan)開時(shi)(shi)，通過p溝(gou)(gou)道MOSFET選(xuan)擇(ze)電(dian)池。

　　MAX17435MAX17535采用(yong)節(jie)省空間的4mmx4mm、24引腳TQFN封(feng)裝，封(feng)裝背部帶(dai)有裸焊盤。器件工作在-40°C至+85°C擴(kuo)展級溫度范圍。可提供(gong)帶(dai)有推薦外部元(yuan)件的評(ping)估板，以(yi)加(jia)速(su)設計進程。
