The Texas Instruments bq27520-G4 system-side LiIon battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell Li-Ion battery packs. The device requires little system microcontroller firmware development. The bq27520G4 resides on the system's main board and manages an embedded battery (non-removable) or a removable battery pack. The bq27520-G4 uses the patented Impedance TrackTM algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), run-time to empty (min), battery voltage (mV), temperature (°C) and state of health (%). Battery fuel gauging with the bq27520-G4 requires only PAC...
