產品總覽
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.
- Single series cell Li-ion battery fuel gauge
- Resides on system board
- Supports embedded or removable batteries
- Powered directly from battery with integrated LDO
- Battery fuel gauging based on patented impedance Track™ technology
- Battery state-of-health (Aging) estimation
- Configurable SOC interrupt or battery low digital output warning
- Internal temperature sensor or host-reported temperature
- Green product and no Sb/Br
