BQ27220 – Single cell pack/system-side CEDV battery fuel (gas) gauge w/pre-programmed chemistry profiles

https://www.electronics-lab.com/bq27220-single-cell-pack-system-side-cedv-battery-fuel-gas-gauge-w-pre-programmed-chemistry-profiles/

The Texas Instruments bq27220 battery fuel gauge is a single-cell gauge that requires minimal user configuration and system microcontroller firmware development, leading to quick system bring-up. The bq27220 device uses the Compensated End-of-Discharge Voltage (CEDV) algorithm for fuel gauging and provides information such as remaining battery capacity (mAh), state-of-charge (%), runtime-to-empty (min), battery voltage (mV), […]
