Battery Fuel Gauges
Maxim’s highly accurate gauges are needed to avoid surprise shutdowns and for a positive user experience
Image of Maxim Integrated's Battery Fuel GaugesMaxim’s battery fuel gauges, also known as battery gas gauges, ascertain battery state-of-charge (SOC) and state-of-health. A battery fuel gauge IC can predict how much longer the battery can continue to provide power under specific operating conditions. Common complaints about any battery-powered device include inadequate battery life and unreliable battery SOC reporting. Users need highly accurate battery fuel gauges to avoid surprise shutdowns for a critical positive user experience.
