Product details

Single-cell fuel gauge with authentication

The Texas Instruments BQ27350PWR is a single-cell Li-ion/polymer battery fuel gauge from the Impedance Track™ series. 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.

Frequently asked questions

Is BQ27350PWR obsolete or NRND?

It is not yet fully obsolete, but TI advises against using it in new product designs.

Can I use BQ27350PWR in a new design?

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.
