The Texas Instruments bq27421-G1 fuel gauge is a minimally configured microcontroller peripheral that provides system-side fuel gauging for single-cell LiIon batteries. The device requires very little user configuration and system microcontroller firmware development. The bq27421-G1 fuel gauge uses the patented Impedance TrackTM algorithm for fuel gauging, a.
