The BQ27421YZFT-G1B is a system-side Fuel Gauge With integrated sense resistor/battery gas gauge. It is a minimally configured microcontroller peripheral that provides system-side fuel gauging for single-cell Li-ion batteries. The device requires very little user configuration and system microcontroller firmware development. The BQ27421-G1 fuel gauge uses the patented Impedance TrackTM algorithm for fuel gauging and provides information such as remaining battery capacity (mAh), state-of-charge (%) and battery voltage (mV). Battery fuel gauging with the fuel gauge requires connections only to PACK+ (P+) and PACK- (P-) for a removable battery pack or embedded battery circuit.
