Product overview
Description
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.
