It communicates over I²C, making it a straightforward addition to any host controller that already has an I²C bus. The 15-DSBGA package (15-UFBGA, DSBGA) keeps the footprint small — critical for space-constrained portable designs. ## Temperature grade and its procurement impact It does not reach automotive temperature extremes (125°C) like the BQ79612PAPRQ1, so if your application sees under-hood or engine-bay heat, you need the automotive-grade sibling. ## Packaging options for reflow planning For rework, a hot-air nozzle with a fine tip and X-ray inspection after placement are standard. ## Lifecycle and compliance posture ROHS3 compliant, which covers the latest EU exemption updates.","metaTitle":"BQ27320YZFT Battery Monitor IC – Texas Instruments, 15-DSBGA","metaDescription":"BQ27320YZFT: Texas Instruments single-cell Li-ion battery monitor, I²C interface, 15-DSBGA package, -40°C to 85°C.

For exact parametric differences, compare the datasheets — the BQ27320 uses TI's Impedance Track™ technology, whereas the BQ27421 uses a simpler voltage-based algorithm. No direct pin compatibility."},{"question":"How to program BQ27320YZFT?","answer":"The BQ27320 is configured via I²C registers. Texas Instruments provides the bqStudio software tool and a USB-to-I²C adapter (EV2400 or similar) for initial setup and data logging. The device ships with default calibration; application-specific parameters (design capacity, taper rate, etc.) are written through the I²C interface."},{"question":"Is BQ27320YZFT RoHS compliant?","answer":"Yes, it is ROHS3 Compliant, covering the latest ROHS exemption categories."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ27320YZFT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ27320YZFT when reusing this data.
