It integrates battery authentication and communicates over an I²C interface, making it suitable for portable devices where pack security and accurate state-of-charge reporting are required. ## NRND — plan for a replacement This means TI has flagged it for eventual discontinuation; new designs should target a current-generation fuel gauge. Existing production lines can continue to source through independent distribution while stock lasts. ## Package and temperature range The surface-mount footprint is standard for this pin count.","metaTitle":"BQ27350PWR Battery Fuel Gauge, Impedance Track, I²C, NRND","metaDescription":"Texas Instruments BQ27350PWR single-cell Li-ion/polymer fuel gauge with Impedance Track and battery authentication.
