Product details

Single-cell Li-Ion charger with I²C programmability

The Texas Instruments BQ24196RGER is a single-cell (1S) Lithium Ion/Polymer battery charger controlled over an I²C interface, delivering up to 2.5 A of programmable charge current from a supply rail rated to 17 V max. The constant-current/constant-voltage profile is set via I²C registers, with the battery regulation voltage fixed at 4.2 V. Integrated fault protection covers over-current, over-temperature, and over-voltage conditions, reducing external supervisory circuitry.

Thermal and package considerations

The 24-VFQFN package with exposed pad is surface-mount.

Frequently asked questions

What is the difference between BQ24196RGER and BQ24195RGER?

The BQ24196RGER and BQ24195RGER are both single-cell I²C-controlled chargers in the same family. The key difference is the battery regulation voltage: BQ24196RGER is fixed at 4.2 V, while BQ24195RGER offers a programmable regulation voltage up to 4.4 V. Verify the BQ24195RGER datasheet for the exact programmable range.

Can BQ24196RGER charge two cells in series?

No, the BQ24196RGER is designed for single-cell (1S) Li-Ion/Polymer batteries only. It does not support 2S or higher series configurations.
