4 Summary

Texas Instruments' gauges with the Impedance Track™ algorithm are widely used in smartphones, notebooks, wearables, and even industrial applications. For all TI gauges with the Impedance Track algorithm, a correct Chem ID and learning is necessary before mass production, which can take several weeks. This application note provides a new method for users who are familiar with TI gauges and have experience on production. This method helps to save approximately 1-2 weeks on design; starting from initial Chem ID configuration to the creation of golden mass production files and battery pack sample manufacturing.
