It monitors charge and discharge through an integrated coulomb counter and reports state-of-charge, voltage, current, and temperature over an HDQ or I²C serial bus. On-chip fault protection covers overcurrent, overtemperature, over/under voltage, and short-circuit conditions — the gauge can trigger a protection FET or alert the host without an external supervisor IC. ## Package and board-fit — 15-DSBGA The 15-DSBGA footprint is smaller than a QFN alternative, which helps in space-constrained portable designs.","metaTitle":"BQ27741YZFR-G1 Texas Instruments Battery Fuel Gauge, Active","metaDescription":"Texas Instruments BQ27741YZFR-G1 multi-function Li-Ion battery fuel gauge.
