Communication runs over an I²C interface, making it a drop-in for portable designs that already have a two-wire bus. ## What the 1S cell limit means for your BOM This part is hard-limited to a single series cell. It cannot be used on 2S or higher battery packs — the internal algorithm and voltage divider assume a single Li-ion cell voltage range. If your design needs a 2S gauge, you need a different part in the BQ274xx family. The Impedance Track algorithm learns the cell's impedance over time, giving more accurate remaining-capacity readings than a simple voltage-based coulomb counter. It is optimised for lithium-ion chemistry and does not support LiFePO4 or NiMH without a different gauge IC. ## Package and mounting Housed in a 12-VFDFN exposed-pad package (also listed as 12-SON 2.5x4mm), this is a no-lead package with a thermal pad underneath. Reflow is the intended assembly method — hand-soldering is difficult without a hot-air station. Cut-tape options are available for prototyping.","metaTitle":"BQ27411DRZR-G1C Battery Monitor, Impedance Track, 1S Li-ion","metaDescription":"Texas Instruments BQ27411DRZR-G1C single-cell Li-ion battery monitor with Impedance Track algorithm.

A 3.7V nominal Li-ion cell (4.2V full) is exactly what this single-cell monitor is designed for. It handles the full voltage range of a standard Li-ion cell."},{"question":"What is the difference between BQ27411DRZR-G1C and BQ27411DRZR-G2?","answer":"The -G1C and -G2 suffixes indicate different firmware/configuration variants within the same base BQ27411 family. The -G1C is the standard Impedance Track gauge for 1S Li-ion. The -G2 may have different default settings or chemistry profiles — check the TI product folder for the specific configuration difference. Both share the same pinout and package."},{"question":"Can BQ27411DRZR-G1C be used with 2S batteries?","answer":"No. This part is strictly a single-cell (1S) monitor. It cannot measure a 2S series stack — the internal voltage range and algorithm assume one cell. For 2S you need a different gauge IC designed for multi-cell packs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ27411DRZR-G1C","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ27411DRZR-G1C when reusing this data.
