Storing Battery Fuel Gauge Parameters in DS2780

Abstract: The DS2780 allows the user to customize the stand-alone battery fuel gauge to the exact requirements of the application and the cell being used. The parameters required are typically known in units such as mA, V, mAhrs, and mΩ. The DS2780 requires that the parameters are stored in units such as uV, uVhrs and mhos. This application note describes the calculations involved in converting the typical units into units that are stored in the device.

Abstract: The DS2780 allows the user to customize the stand-alone battery fuel gauge to the exact requirements of the application
and the cell being used. The parameters required are typically known in units such as mA, V, mAhrs, and mΩ. The DS2780
requires that the parameters are stored in units such as uV, uVhrs and mhos. This application note describes the calculations
involved in converting the typical units into units that are stored in the device.


Introduction
The DS2780 standalonebattery fuel gaugeis simple to use and very accurate, assuming the correct parameters for the application
have been stored in this device. It is very important that the correct data be stored so that the fuel gauge is optimized. The
