描述

ISL78714 汽车级锂离子电池管理器 IC 可监控多达14个串联电池,经过优化以满足严格的汽车性能、可靠性和安全性要求。该器件提供了电池管理系统中此类关键部件的所有功能,如精确的电池电压和温度监控、电池平衡和广泛的系统诊断。

在典型配置中,主 ISL78714 通过 SPI 端口和多达 29 个附加 ISL78714 器件通过一个可靠的专用双线菊花链连接在一起,与主机微控制器通信。这个通信系统非常灵活,可以用电容器隔离、变压器隔离或两者结合来实现。

包括三种电池平衡模式:手动平衡模式、定时平衡模式和自动平衡模式。自动平衡模式在从每个电池中消耗主机指定的电量后终止平衡。

ISL78714 封装在 64 引脚 TQFP 中,规定的工作温度范围为 -40°C 到 +105°C。
