開關(guān)模式鋰離子電池充電器

MAX745提供為鋰離子電池組充電所需的所有功能。它提供高達(dá)4A的調(diào)節(jié)充電電流且不會變熱，電池端子處的調(diào)節(jié)電壓總誤差僅為±0.75%。它使用低成本的1%電阻來設(shè)置輸出電壓，并使用低成本的N溝道MOSFET作為電源開關(guān)。\n\n MAX745使用兩個環(huán)路調(diào)節(jié)電壓設(shè)定點和充電電流，這兩個環(huán)路協(xié)同工作以在電壓和電流調(diào)節(jié)之間平穩(wěn)轉(zhuǎn)換。使用標(biāo)準(zhǔn)1%電阻將每節(jié)電池的電壓調(diào)節(jié)限值設(shè)置在4V至4.4V之間，然后通過引腳綁定將電池數(shù)量設(shè)置為1到4節(jié)。輸出電壓總誤差小于±0.75%。\n\n 對于具有SMBus?微控制器接口并能夠為鎳鎘和鎳氫電池充電的類似器件， ? 為1至4節(jié)鋰離子電池充電\n\n? 使用1%電阻時電壓調(diào)節(jié)精度為±0.75%\n\n? 提供高達(dá)4A的電流而不會過熱\n\n? 90%效率\n\n? 使用低成本設(shè)置電阻和N溝道開關(guān)\n\n? 高達(dá)24V輸入\n\n? 最大電池電壓高達(dá)18V\n\n? 300kHz脈寬調(diào)制(PWM)工作模式\n? 低噪音、小型元件\n\n\n\n\n? 獨立工作——無需微控制器;
