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.
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.
It is not yet fully obsolete, but TI advises against using it in new product designs.
TI does not recommend using the BQ27350PWR in new designs due to its NRND status. Existing production may continue while supply lasts through independent distribution.
