Battery monitoring with alarm output for gas gauge applications based on the STC3115

The STEVAL-ISB014V2 product evaluation board is based on the STC3115. This device includes the hardware functions required to implement a low-cost gas gauge for battery monitoring. It uses current sensing, Coulomb counting and accurate battery voltage measurements to estimate the state-of-charge (SOC) of the battery. An internal temperature sensor simplifies implementation of temperature compensation.

An alarm output signals a low SOC condition and can also indicate low battery voltage. The alarm threshold levels are programmable.

The STC3115 offers advanced features to ensure high performance gas measurement in all application conditions.

The STEVAL-ISB014V2 evaluation board is suitable for portable medical equipment, mobile phones, multimedia players and digital cameras.
