BQ40Z80 器件采用已获专利的 Impedance Track™ 技术，是一个全集成、单芯片、基于电池组的解决方案，可为 2-6 节串联锂离子和锂聚合物电池组提供电量监测、保护和认证等各种特性。
BQ40Z80 器件利用其集成的高性能模拟外设，测量锂离子或锂聚合物电池的可用容量、电压、电流、温度和其他关键参数，保留准确的数据记录，并通过 SMBus v1.1 兼容接口将这些信息报告给系统主机控制器。
椭圆曲线加密 (ECC) 或 SHA-1 认证具有用于认证密钥的安全存储器，可确保识别真正的电池组。
BQ40Z80 器件为主机系统提供可用的最大功率和最大电流，从而支持涡轮模式 2.0/Intel 动态电池功率技术 (DBPTv2)。该器件有八个多功能引脚，可配置为热输入、ADC 输入、通用输入/输出 (GPIO) 引脚、Presence 引脚、LED 功能、显示按钮输入或其他功能。状态和标志寄存器可映射到 GPIO，并用作主机处理器的中断。
Please use this device as a 2S to 6S battery pack manager.
