Description

The STC3115 includes the hardware functions

required to implement a low-cost gas gauge for

battery monitoring. The STC3115 uses current

sensing, Coulomb counting and accurate

measurements of the battery voltage 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 gauging in all application

conditions.
