bq35100 Battery Fuel Gauge & EOS Monitor Texas Instruments bq35100 Battery Fuel Gauge & EOS Monitor provides highly configurable fuel gauging for non-rechargeable lithium primary batteries—without requiring forced discharge of the battery. Built so that optimisation is not necessary, the patented TI gauging algorithms support replaceable batteries. They also enable 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 to make calculations to support the selected algorithm and the frequency of updates required by the system.Learn more
