bq35100 Battery Fuel Gauge & EOS Monitor

Texas Instruments bq35100 Battery Fuel Gauge and EOS Monitor provide highly configurable fuel gauging for non-rechargeable lithium primary batteries without requiring the forced discharge of the battery. Built so that optimization is not necessary, the patented TI gauging algorithms support replaceable batteries. The device also enables accurate results with ultra-low average power consumption through host control via the GAUGE ENABLE (GE) pin. The fuel gauging functions use voltage, current, and temperature information to provide State-Of-Health (SOH) and End-Of-Service (EOS) data. The bq35100 device is only required to be powered long enough to gather data and make calculations to support the selected algorithm and the frequency of updates required by the system.
