It reports remaining capacity and time-to-empty to the host processor — the data you need for a low-battery warning or graceful shutdown in a portable device. The HDQ and I²C interface lets you talk to most MCUs without a dedicated translator; just confirm the bus voltage levels match your host's I/O rail. ## Package and mounting — the board-level reality Housed in a 15-bump DSBGA (15-UFBGA), the BQ27545YZFT-G1 requires a surface-mount assembly with a fine-pitch BGA process. The base product number BQ27545 covers this variant; the -G1 suffix denotes the specific configuration.","metaTitle":"BQ27545YZFT-G1 Battery Monitor IC - TI Impedance Track™","metaDescription":"Texas Instruments BQ27545YZFT-G1 single-cell Li-ion battery fuel gauge.
