Product details

Single-cell Li-ion fuel gauge with Impedance Track

The Texas Instruments BQ27411DRZR-G1A is a single-cell Lithium Ion battery monitor that uses the Impedance Track™ algorithm to report state-of-charge, voltage, and current over an I²C interface. It is designed for portable devices where accurate remaining-capacity estimation matters more than a simple voltage-based fuel gauge — the Impedance Track method compensates for cell aging, temperature, and discharge rate.

12-SON package and hand-solder feasibility

Housed in a 12-VFDFN exposed-pad package (12-SON, 2.5x4 mm). Hand-soldering is possible with a fine-tip iron and careful flux application, but the small pad pitch and exposed paddle make a reflow profile the reliable production method.

Frequently asked questions

Does the BQ27411DRZR-G1A support 2S Li-ion packs?

No. This part is designed for single-cell (1S) Lithium Ion applications only. It does not support 2S or higher series configurations.
