The 15-DSBGA package (0.5 mm pitch typical for this class) means the PCB layout must account for the fine-pitch BGA fan-out — a 2-layer board is tight; 4-layer with microvias is the safer call for production yield. ## Active lifecycle and sourcing No lead-time number here, but the active status means the factory pipeline is open.","metaTitle":"TI BQ27531YZFR-G1 Battery Fuel Gauge, Impedance Track, I²C","metaDescription":"Texas Instruments BQ27531YZFR-G1 single-cell Li-ion battery fuel gauge with Impedance Track technology, I²C interface, 15-DSBGA, -40°C to 85°C.

These parts are not drop-in substitutes; a BOM designed around the BQ27531YZFR-G1 requires a different IC for protection and a different PCB footprint (15-DSBGA vs the DSGT package)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ27531YZFR-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/BQ27531YZFR-G1 when reusing this data.
