STC3115AIQT Description
The STC3115AIQT from STMicroelectronics offers the hardware functionality needed to construct a low-cost gas gauge for battery monitoring. The STC3115 estimates the battery's state of charge (SOC) via current sensing, Coulomb counting, and precise voltage measurements. The use of an internal temperature sensor facilitates temperature compensation installation.
