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.
