Description
The bq35100 Battery Fuel Gauge and End-OfService Monitor provides highly configurable fuel gauging for non-rechargeable lithium primary batteries—without requiring forced discharge of the battery. Built so that optimization is not necessary, the patented TI gauging algorithms support replaceable batteries and 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. The host can read the gathered data through a 400kHz I2C bus. An ALERT output is also available to interrupt the host, based on a variety of configurable options.
