Integrated gas gauge IC with alarm output for battery-monitoring applications

07-01-2015 | Mouser Electronics | Power

Suitable for applications such as wearables, fitness, healthcare and portable medical equipment, Mouser is now stocking the STMicroelectronics GG25L, a gas gauge IC with alarm output and the hardware functions required to implement a low-cost 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, says the company.
