It communicates over HDQ or I²C to a host controller, reporting state-of-charge, voltage, and remaining capacity. The 14-TSSOP package keeps the footprint small for embedded battery-management boards in UPS systems, backup power units, and industrial equipment where lead-acid is the incumbent chemistry. ## What the ratings mean for the BOM The Impedance Track algorithm compensates for discharge rate, temperature, and cell aging — the accuracy a calibration technician expects from a fuel gauge that tracks impedance changes over the battery's life, not just voltage lookup. The -40°C to 85°C operating range covers outdoor telecom enclosures and unheated factory floors; the part does not require a heated enclosure for winter operation. The HDQ and I²C interface options give the firmware engineer flexibility: HDQ uses a single-wire bus for minimal pin count, I²C for standard multi-device bus integration. The 14-TSSOP package is a 4.40 mm wide body, common for this pin count, and the surface-mount footprint suits automated assembly lines. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"BQ34Z110PW Lead-Acid Fuel Gauge, Impedance Track, 14-TSSOP","metaDescription":"TI BQ34Z110PW lead-acid battery monitor with Impedance Track algorithm, HDQ/I²C interface, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"Impedance Track™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Impedance Track™","Package":"Tube","Function":"Battery Monitor","Interface":"HDQ, I²C","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Battery Chemistry":"Lead Acid","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"14-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.93","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.93000","currency":"USD"},{"qty":10,"price":"$7.16300","currency":"USD"},{"qty":25,"price":"$6.82960","currency":"USD"},{"qty":100,"price":"$5.93020","currency":"USD"},{"qty":250,"price":"$5.66368","currency":"USD"},{"qty":500,"price":"$5.16394","currency":"USD"},{"qty":1000,"price":"$4.71450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0ba46537bbb76d00317a5cde2af70456.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can BQ34Z110PW be used with 24V lead acid?","answer":"Yes — the BQ34Z110PW is a lead-acid battery monitor, and the Impedance Track algorithm scales to support multi-cell series stacks including 24V nominal banks. Verify the specific voltage range against the full datasheet for your cell count."},{"question":"How does BQ34Z110PW compare to BQ34Z100?","answer":"The BQ34Z100 is a newer generation lead-acid fuel gauge with similar Impedance Track core but updated firmware and register map. The BQ34Z110PW is an established variant; check the TI application note for migration differences if you are cross-shopping the two."},{"question":"What is the accuracy of BQ34Z110PW?","answer":"Accuracy depends on the Impedance Track algorithm's learning cycle and the quality of the battery-characterization data loaded during calibration. The algorithm compensates for temperature, discharge rate, and aging — typical state-of-charge error is within a few percent after a full learning cycle, but the exact figure requires a traceable verification against a calibrated load and reference meter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ34Z110PW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ34Z110PW when reusing this data.
