It monitors state-of-charge and reports battery data to a host controller in portable equipment. The device operates across -40°C to 85°C, suiting it for outdoor handhelds, medical monitors, and industrial instrumentation where the battery pack sees ambient extremes. ## I²C bus and host integration The BQ27541DRZR-V200 uses the I²C interface to deliver battery parameters — voltage, current, temperature, remaining capacity — to a system MCU. A single-cell Li-Ion pack is the target; the gauge handles one series cell. Over-temperature fault protection is built in, which can trigger a host alert or shutdown if the pack exceeds a safe threshold. ## Package and board footprint Surface-mount assembly with standard reflow profile; the small SON footprint saves board area in tight battery-pack or handheld designs. ## Lifecycle and supply position It is a current-production TI part, so production BOMs are not facing an imminent last-time-buy.","metaTitle":"BQ27541DRZR-V200 Impedance Track™ Fuel Gauge, I²C","metaDescription":"TI BQ27541DRZR-V200 single-cell Li-Ion fuel gauge with Impedance Track™, I²C interface, -40°C to 85°C range, 12-VFDFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"$6.6000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fbq27541-v200","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between BQ27541DRZR-V200 and BQ27541DRZR-V100?","answer":"The V200 and V100 are firmware-version variants of the same base BQ27541 fuel gauge.
