validate and test their design implementation to confirm system functionality.
8.1 Application Information
The bq4050 gas gauge has primary protection support to be used with a 1-series to 4-series Li-Ion/Li Polymer
battery pack. To implement and design a comprehensive set of parameters for a specific battery pack, users
need the Battery Management Studio (bqStudio) graphical user-interface tool installed on a PC during
development. The firmware installed on the bqStudio tool has default values for this product, which are
summarized in the bq4050 Technical Reference Manual (SLUUAQ3). Using the bqStudio tool, these default
values can be changed to cater to specific application requirements during development once the system
parameters, such as fault trigger thresholds for protection, enable/disable of certain features for operation,
configuration of cells, chemistry that best matches the cell used, and more are known. This data is referred to as
the "golden image."
