簡單的限流型開關(guān)模式Li+充電控制器

低成本的MAX1873R/S/T提供了簡單、高效地為2、3、4節(jié)串聯(lián)鋰電池充電所需要的全部功能，充電電流可達4A或更高。它能夠以低于±0.75%的總計電壓誤差(電池端)提供穩(wěn)定的充電電流和電壓。在這一低成本設(shè)計中，利用由外置P溝道MOSFET組成的開關(guān)降壓電路對電池高效充電。\n\n MAX1873R/S/T利用兩個同時工作的控制環(huán)路平滑地在電壓和電流調(diào)制間過渡調(diào)節(jié)電池電壓和充電電流。另包括一控制回路限制輸入電源電流，這樣就可以減小AC適配器的體積和成本開銷。正比于充電電流的模擬電壓輸出使得可以使用ADC或是微控制器監(jiān)控充電電流。\n\n MAX1873也可以用做高 ? 低成本和簡單的電路\n? 給2、3、4節(jié)串聯(lián)鋰電池充電\n? 有AC適配器輸入電流限制回路\n? 也可以用于鎳基電池充電\n? 模擬輸出監(jiān)控充電電流\n? ±0.75%電池電壓調(diào)節(jié)\n? 5μA關(guān)斷電池電流\n? 高達28V的輸入電壓\n? 200mV壓差/100%占空比\n? 可調(diào)節(jié)充電電流 \n? 300kHz PWM振蕩器以減少噪聲\n? 節(jié)省空間的16引腳QSOP封裝\n?
