Get Enhanced Safety, Accurate State-of-Charge and Longer Runtime for Your Portable Device Battery


Abstract: Accurate battery state-of-charge (SOC), long runtime and shelf life, and safety are critical considerations when developing portable devices. A new, highly integrated family of fuel-gauge ICs addresses these battery challenges. By implementing the ModelGauge™ m5 EZ algorithm, the MAX17301 eliminates battery characterization, greatly improving time-to-market (TTM). The algorithm leads to an accurate prediction of SOC and enhanced safety. Furthermore, the low quiescent current of the IC allows for longer shelf life and longer run-time. Integration of fuel gauge and protection control enhances safety and minimizes the bill-of-materials (BOM) and PCB area.
