Its key advantage is the patented algorithm that learns the battery's impedance over charge/discharge cycles, delivering state-of-charge accuracy that improves with use rather than drifting — no full discharge recalibration needed. It is ROHS3 compliant. The base product number is BQ27541. ## Fault protection and chemistry match Integrated over-temperature fault protection monitors the die temperature, not the cell — so the thermistor input on the host side is still needed for pack-level thermal supervision. The gauge is pre-configured for Lithium Ion chemistry; no chemistry profile selection is required at startup.","metaTitle":"BQ27541DRZT Texas Instruments Battery Fuel Gauge","metaDescription":"BQ27541DRZT from Texas Instruments — single-cell Li-ion fuel gauge with Impedance Track™ algorithm, I²C interface, -40°C to 85°C range, 12-VFDFN package.","metaKeywords":null},"attributes":{"series":"Impedance Track™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Impedance Track™","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Multi-Function Controller","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"12-VFDFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion","Base Product Number":"BQ27541","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"12-SON (2.5x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.0500","priceTiers":[{"qty":1,"price":"$8.05000","currency":"USD"},{"qty":10,"price":"$7.26800","currency":"USD"},{"qty":25,"price":"$6.92960","currency":"USD"},{"qty":100,"price":"$6.01700","currency":"USD"},{"qty":250,"price":"$5.74656","currency":"USD"},{"qty":500,"price":"$5.23952","currency":"USD"},{"qty":1250,"price":"$4.78350","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ27541DRZT/alternatives.json"},"ai":{"faq":[{"question":"Is the BQ27541DRZT a replacement for the BQ27541DRZR?","answer":"The BQ27541DRZT and BQ27541DRZR share the same base product number BQ27541. The suffix difference typically indicates packaging or tape/reel variant. Confirm the exact ordering code with your BOM — the DRZT is listed in Tape & Reel (TR) and Cut Tape (CT) options."},{"question":"What is the closest functional alternative to the BQ27541DRZT?","answer":"The BQ79612PAPRQ1 is a different device — it is an automotive-grade battery monitor with SPI/UART interface and AEC-Q100 qualification, not a direct fuel-gauge replacement.
