TI introduces fuel gauge to protect lithium-ion batteries

Texas Instruments has unveiled the bq27741 pack-side battery fuel gauge with Impedance Track monitoring algorithm and high-side sense resistor. Available in a 15-bump chip scale package measuring 1.9-mm by 2.7-mm by 0.6-mm, the fuel gauge offers protection to single-cell lithium-ion batteries designed for limited spaces.

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 Impedance Track algorithm accurately reports 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 minimising configuration and system firmware development.
