Single-cell Li-ion fuel gauge in a DSBGA footprint
The BQ27320YZFT is a battery monitor IC from Texas Instruments designed for single-cell Lithium Ion battery packs. 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.
