GG25LAJ

STMicroelectronics' GG25LAJ Gas Gauge IC with Alarm Output includes the hardware functions required to implement a low-cost gas gauge for battery monitoring. The GG25LAJ 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 GG25LAJ offers advanced features to ensure high-performance gas gauging in all application conditions.
