It communicates over an I²C interface to the host MCU, reporting voltage, current, temperature, state of charge, and remaining capacity. ## 12-SON package — rework and layout notes The BQ27410DRZT-G1 comes in a 12-VFDFN exposed-pad package, supplier code 12-SON (2.5x4 mm). That exposed pad is the thermal and electrical ground — it needs a solid via-stitched copper pour on the top layer, and the datasheet's recommended footprint is tight. For rework: the small body and exposed pad make it a hot-air job. Tack the corner pins first to align, then flow the pad with a hot-air nozzle at 300°C. Will it survive the hot air? Yes, if the board copper doesn't act as a heat sink. The base product number is BQ27410, so any future variant shifts (package or tape orientation) will carry a different suffix, not a die change.","metaTitle":"TI BQ27410DRZT-G1 Battery Fuel Gauge, Impedance Track","metaDescription":"Texas Instruments BQ27410DRZT-G1 single-cell LiCoO2 battery fuel gauge with Impedance Track algorithm.

The BQ27410 is configured for single-cell Lithium Cobalt Oxide chemistry. The BQ27411 targets a different chemistry profile or cell configuration — verify the datasheet's chemistry and cell-count tables before substituting. The package and pinout may differ."},{"question":"How does Impedance Track work?","answer":"Impedance Track is a battery fuel-gauging algorithm that continuously learns the battery's impedance as a function of temperature, state of charge, and age. Instead of relying on a fixed lookup table, it updates the model during normal discharge and charge cycles, so the remaining-capacity estimate stays accurate even as the cell degrades over hundreds of cycles."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ27410DRZT-G1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ27410DRZT-G1 when reusing this data.
