The 12-DSBGA package measures roughly 2.2 mm x 2.0 mm — the board layout must route the I²C lines away from switching noise on the battery path. The Impedance Track™ algorithm compensates for cell aging and temperature, so the gauge stays accurate over the battery's service life without periodic full-cycle recalibration. It is ROHS3 compliant, which simplifies EU and California market entry. The base product number is BQ27505, so future variant changes (e.g., firmware revision) will share the same footprint.","metaTitle":"BQ27505YZGT-J5 TI Impedance Track™ Battery Fuel Gauge","metaDescription":"Texas Instruments BQ27505YZGT-J5 single-cell Li-Ion battery monitor with Impedance Track™, I²C interface, -40°C to 85°C.
