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.
