Architectural overview

The system architecture has been separated into two main parts in order to facilitate the

most flexible integration. The STC3115 takes physical measurements and reports the

battery state of charge (SOC) through I²C interface while the software layer is concerned

with battery parameter initialization and compensation using all the dedicated features of

the chipset.

Depending on the targeted accuracy of the application environment, the STC3115 can be

used alone without software compensation. In this configuration, the application software

uses only the STC3115 register information to display the battery SOC to the user. If the

temperature and aging effects need to be compensated, the software layer uses the

STC3115 dedicated features.
