bq79606-Q1器件可针对三到六节电池提供同步,高精度的通道测量。通过加入菊花链通信端口,bq79606-Q1器件可通过堆叠方式(最多51个器件)支持电气化汽车传动系电池组中的大型堆叠配置.bq79606-Q1为每个电池输入提供一个Δ-Σ转换器,支持同时测量电池电压,提供电池电压的真实快照。
bq79606-Q1包含一个辅助ADC,可支持多达6个NTC的电池温度测量,并可通过内部电压轨实现针对器件的安全检查。此器件还包括一个裸片温度测量ADC,用于提供温度校正,以便在扩展温度范围内获得高精度结果。
主机与bq79606-Q1器件之间的通信通过UART专用接口实现。此外,一个支持电容器和变压器隔离的隔离式差分UART菊花链通信接口允许主机通过单个接口即可与整个电池堆叠进行通信。这个菊花链通信接口配置为环形架构,许主机在通信线路中断的情况下与堆叠任一端的器件进行通信。
