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.","metaTitle":"BQ27510DRZT-G3 Battery Monitor, Impedance Track™, I²C","metaDescription":"TI BQ27510DRZT-G3 single-cell Li-ion battery monitor with Impedance Track™ algorithm.

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."},{"question":"What is the difference between BQ27510DRZT-G3 and BQ27510DRZR?","answer":"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."},{"question":"What is the difference between Impedance Track and coulomb counting?","answer":"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."},{"question":"How to calibrate BQ27510?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ27510DRZT-G3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ27510DRZT-G3 when reusing this data.
