Single-chip battery gauge offers integrated protection in a chipscale package
The device accurately monitors and protects single-cell Li-Ion batteries used in space-constrained designs.
The bq27741 pack-side fuel gauge uses TI’s proprietary Impedance Track monitoring algorithm to boost battery run-time in consumer and portable industrial and medical devices. The device features an Impedance Track algorithm to accurately report remaining battery capacity, state-of-health, state-of-charge and battery voltage.
The bq27741’s high-side sense resistor allows the use of one common ground plane and removes offset and noise, which saves cost and board space. The device also provides high-accuracy fault detection and shutdown circuitry for better safety margins, including the use of full-cell voltage and charging range without false trips.
Designers can simplify battery gauging design with the bq27741 fuel gauge by using TI’s new Gauge Studio software tool. The file size of the Gauge Studio design tool is about ten times smaller than TI’s previous software, dramatically minimizing configuration and system firmware development.
