- STC3115
For battery-powered systems the challenge is to precisely predict the remaining time before recharge. STC3115 innovates proposing low power state-of-charge estimation with long-term accuracy by self-adapting to both aging and temperature changes.
STC3115 features patented innovations. It performs both coulomb counting and periodic voltage-mode state-of-charge measurements to adjust the Coulomb counter for accuracy.
The STC3115 uses both sets of measurements continuously with OptimGauge
, an adaptive algorithm that tracks the state of charge and corrects the battery model all along the battery lifetime.
It is available in a 1.4 x 2.0 mm package.
