9 Applications and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

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."
