BQ27441DRZT-G1A

The BQ27441DRZT-G1A is a Battery Fuel (Gas) Gauge that provides system-side fuel gauging for single-cell Li-ion batteries. The device requires minimal user configuration and system microcontroller firmware development. The bq27441-G1 battery 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). Battery fuel gauging with the bq27441-G1 fuel gauge requires connections only to PACK+ (P+) and PACK- (P-) for a removable battery pack or embedded battery circuit.
