System-Side Impedance Track ™ Fuel Gauge

The Texas Instruments bq27505 system-side Li-Ion 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 bq27505 resides on the system ’ s main board and manages an embedded battery (non-removable) or a removable battery pack. The bq27505 uses the patented Impedance Track ™ 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 (%).
