Battery Fuel Gauges
Analog Devices’ highly accurate gauges are needed to avoid surprise shutdowns and for a positive user experience
Analog Devices’ 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.
Analog Devices' battery fuel gauges have been successfully used in over one billion devices. Time-to-empty, time-to-full, battery age forecasting, and dynamic power features extend the run-time of transient loads.
Features
- Highest accuracy SOC reporting, even in very low temperatures and very high load conditions
- Low quiescent current for low-power applications such as wearables
- Strong SHA-256 authentication to prevent counterfeit battery packs
- Communication interfaces: I2C, 1-wire, and SMBus
- Integrated protection to save space and simplify battery pack design
- Easy setup without battery characterization (ModelGauge™ m5 EZ)
- Easy manufacturability with short programming times and no calibration
Applications
- Smartphones
- Tablets
- AR/VR glasses
- mPOS (mobile point-of-sale)
- Smartwatches
- Health and fitness monitors
- Portable game players
- Power tools
- Toys
