使用DS2751电池电量计在多个电池包应用

摘要： DS2751 Li +电池/镍氢电池电量计IC设计监测单节锂离子（锂离子）或3节镍氢电池组。然而，适当的电路修改， DS2751电量计还可以被用来监测2节锂离子电池。本应用笔记介绍了一个参考电路，可用于执行使用DS2751电池电量计测量2节锂离子电池的剩余容量。详细描述电路的关键部件进行了讨论，其中包括为DS2751本身的配置问题。

APPLICATION NOTE 2046
Using the DS2751 Battery Fuel Gauge in Multiple-Cell Battery Pack
Applications

Abstract: The DS2751 Li+/NiMH battery Fuel Gauge IC is designed to monitor single-cell Lithium-ion (Li-ion) or
3-cell NiMH battery packs. However, with the appropriate circuit modifications, the DS2751 fuel gauge can also
be used to monitor a 2-cell Li-ion battery pack. This application note presents a reference circuit that can be
used to implement the use of the DS2751 battery fuel gauge to measure the remaining capacity of a 2-cell Li-
ion battery pack. Detailed descriptions of the key components of
