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)的條件(jian)下通過SMBus接口對(dui)充(chong)電(dian)(dian)設(she)置(zhi)(zhi)(zhi)進行編程，大大提高了設(she)計(ji)靈(ling)活(huo)性。可編程設(she)置(zhi)(zhi)(zhi)包(bao)括充(chong)電(dian)(dian)電(dian)(dian)流、充(chong)電(dian)(dian)電(dian)(dian)壓、輸入(ru)限流、再學(xue)習電(dian)(dian)壓以(yi)及數字(zi)IINP電(dian)(dian)壓回讀。功能類似的競爭方(fang)案則需使(shi)用外部元件(jian)編程充(chong)電(dian)(dian)設(she)置(zhi)(zhi)(zhi)。MAX17435MAX17535可理想用于(yu)筆記本(ben)電(dian)(dian)腦、超便攜PC(UMPC)、移動互聯網(wang)設(she)備(bei)(MID)及其它(ta)對(dui)空(kong)間尺寸要求嚴格的電(dian)(dian)池供電(dian)(dian)應(ying)用。

　　MAX17435MAX17535可(ke)提供(gong)(gong)±0.4%的電(dian)池電(dian)壓精度。低失調電(dian)流(liu)檢測放大(da)器采用10mΩ檢流(liu)電(dian)阻提供(gong)(gong)±3%的充電(dian)電(dian)流(liu)精度。在接(jie)入適(shi)配器時(shi)，器件內部(bu)的電(dian)荷泵用于(yu)驅動(dong)適(shi)配器n溝道(dao)MOSFET;當適(shi)配器斷開時(shi)，通過p溝道(dao)MOSFET選擇電(dian)池。

　　MAX17435MAX17535采(cai)用節(jie)省(sheng)空間(jian)的(de)4mmx4mm、24引腳TQFN封裝(zhuang)，封裝(zhuang)背部帶有裸焊盤(pan)。器(qi)件(jian)工作在(zai)-40°C至+85°C擴展(zhan)級溫(wen)度范(fan)圍。可(ke)提供(gong)帶有推薦外部元件(jian)的(de)評(ping)估板，以(yi)加(jia)速設計進程(cheng)。
