bq27621-G1 Overview
The Texas Instruments bq27621-G1 is a minimally configured microcontroller peripheral that provides system-side fuel gauging for single-cell Li-Ion batteries. The device requires very little user configuration and system microcontroller firmware development. The bq27621-G1 uses the Dynamic Voltage Correlation algorithm for fuel gauging.
