The BQ27411DRZT-G1C is a pack-side impedance Track™ Fuel Gauge/Battery Gas Gauge for single-series cell Li-ion battery packs. The device requires minimal configuration and uses one time programmable (OTP) non-volatile memory (NVM) to avoid an initialization download by the system processor. The fuel gauge uses the patented Impedance Track™ algorithm for fuel gauging and provides information such as remaining battery capacity (mAh), state-of-charge (%) and battery voltage (mV).
