高级Li+电池组保护器

MAX1894/MAX1924是锂离子/锂聚合物(Li+)电池组保护芯片，用于3节或4节串联Li+电池组。MAX1894/MAX1924监视每节电池的电压并防止出现过压/欠压，有效延长了Li+电池的工作寿命。MAX1894/MAX1924还提供过充电流/过放电流和电池组短路等故障保护。\n 故障发生时，板上驱动器控制外部P沟道MOSFET，断开电池与电池组外接端子。外部MOSFET保护管采用共源连接，无需外接上拉电阻。MAX1894/MAX1924仅使用一个检流电阻即可实现保护功能。所有的保护门限和延迟无需外部元件设置，由工厂预置。\n 如果任何一节电池电压低于欠压门限，MAX1894/MAX \n• ±0.5%精度、4V至4.4V工厂可编程过压保护门限 \n• ±2.0%精度、2V至3.2V工厂可编程欠压保护门限 \n• 过充/过放电流和电池组短路故障保护 \n• 对过放电电池自动涓流充电 \n• 完全集成的MOSFET驱动器无需上拉电阻 \n• 0.8µA (典型值)关断电流防止电池过放电 \n• 30µA (典型值)工作电流 \n• 28V (最大值)输入电压 \n• 采用小尺寸16引脚QSOP封装;
