Product details

Impedance Track™ fuel gauge for single-cell Li-ion packs

The Texas Instruments BQ27510DRZT-G3 is a single-cell lithium-ion battery monitor using the Impedance Track™ algorithm to report state-of-charge and run-time, not just voltage. It communicates over an I²C bus and is packaged in a 12-VFDFN with exposed pad (12-SON 2.5x4 mm) for surface-mount assembly.

Single-cell support means this part is sized for a 1-series Li-ion stack (3.6 V nominal, 4.2 V full). The I²C interface lets a host MCU poll voltage, current, temperature, and remaining capacity without an ADC channel.

Frequently asked questions

Is BQ27510DRZT-G3 compatible with standard lithium-ion batteries?

Yes — it is designed for single-cell Lithium Ion chemistry (3.6 V nominal). The Impedance Track™ algorithm learns the battery's discharge curve over cycles, so it works with any standard Li-ion cell that fits the 4.2 V full-charge profile.

What is the difference between BQ27510DRZT-G3 and BQ27510DRZR?

The suffix distinguishes the tape-and-reel packaging option — DRZT is Tape & Reel (TR) with Cut Tape (CT) availability, while DRZR is a different reel format. The die, firmware, and electrical ratings are identical. Confirm the reel quantity and tape width your assembler needs before ordering.

What is the difference between Impedance Track and coulomb counting?

Impedance Track™ is a TI-patented algorithm that combines voltage, current, temperature, and battery-impedance data to estimate state-of-charge. Basic coulomb counting only integrates current and drifts over time without a full-charge reset. Impedance Track™ self-corrects using the battery's open-circuit voltage and impedance profile, giving accurate remaining-capacity readings across temperature and load without requiring periodic full discharges.

How to calibrate BQ27510?

Calibration involves writing the battery's design capacity, termination voltage, and impedance table parameters via I²C commands. Texas Instruments provides a software tool (bqStudio) and an application note for the calibration sequence — the gauge learns the cell's characteristics over the first few charge-discharge cycles if the initial data matches the cell datasheet.
