The device requires little system microcontroller firmware development. The bq27520-G1 resides on the system's main board and manages an embedded battery (non-removable) or a removable battery pack. The bq27520-G1 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...
