9.1 Application Information
The bq40z50-R2 is a gas gauge with primary protection support, and can be used with 1-series to 4-series Li-
Ion/Li Polymer battery packs. 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 bq40z50-R2 Technical Reference Manual (SLUUBK0). 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."
