高級Li+電池組保護器

MAX1894/MAX1924是鋰離子/鋰聚合物(Li+)電池組保護芯片，用于3節(jié)或4節(jié)串聯(lián)Li+電池組。MAX1894/MAX1924監(jiān)視每節(jié)電池的電壓并防止出現(xiàn)過壓/欠壓，有效延長了Li+電池的工作壽命。MAX1894/MAX1924還提供過充電流/過放電流和電池組短路等故障保護。\n 故障發(fā)生時，板上驅動器控制外部P溝道MOSFET，斷開電池與電池組外接端子。外部MOSFET保護管采用共源連接，無需外接上拉電阻。MAX1894/MAX1924僅使用一個檢流電阻即可實現(xiàn)保護功能。所有的保護門限和延遲無需外部元件設置，由工廠預置。\n 如果任何一節(jié)電池電壓低于欠壓門限，MAX1894/MAX \n? ±0.5%精度、4V至4.4V工廠可編程過壓保護門限 \n? ±2.0%精度、2V至3.2V工廠可編程欠壓保護門限 \n? 過充/過放電流和電池組短路故障保護 \n? 對過放電電池自動涓流充電 \n? 完全集成的MOSFET驅動器無需上拉電阻 \n? 0.8μA (典型值)關斷電流防止電池過放電 \n? 30μA (典型值)工作電流 \n? 28V (最大值)輸入電壓 \n? 采用小尺寸16引腳QSOP封裝;
