Abstract

This application note examines how to configure the BQ35100 for End of Service (EOS) mode to accurately alert when a primary Li-SoCl2 battery needs to be replaced. To optimize the algorithm, impedance data needs to be collected using a microcontroller or other capable system to help calculate the data flash parameters for the EOS algorithm and alert functions.
