The GG25L includes the hardware functions required to implement a low-cost gas gauge for battery monitoring. The GG25L 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 GG25L offers advanced features to ensure high performance gas gauging in all application conditions.
