Product details

2A charge current with programmable timer and current

The BQ24113RHLRG4 is a bqSWITCHER series Li-Ion/Li-Pol battery charger IC from Texas Instruments. It delivers a programmable constant charge current up to 2A for 1 or 2 series cells, with the battery pack voltage regulated to 8.4V. The input supply range extends to 16V, covering most USB and 5V/9V wall adapters without an external pre-regulator.

Industrial temperature range and fault protection

On-chip fault protection includes over-temperature and over-voltage shutdown, reducing external supervisory circuitry.

20-VQFN package — thermal layout matters

Housed in a 20-VFQFN exposed-pad package (3.5x4.5 mm). Surface-mount assembly only.

Frequently asked questions

Is BQ24113RHLRG4 compatible with 1-cell Li-Po batteries?

Yes. The device supports 1 or 2 series cells. For a 1-cell Li-Po (4.2V termination), the battery pack voltage is set by the external resistor divider — the 8.4V figure in the spec table is the maximum for 2-cell operation. The charger regulates to the programmed voltage.

Is BQ24113RHLRG4 an exact replacement for BQ24113RHLR?

The BQ24113RHLR and BQ24113RHLRG4 share the same base product number BQ24113 and the same 20-VQFN package. The 'G4' suffix indicates RoHS compliance and a specific reel packaging variant. Electrically they are identical; the G4 version is the current green/RoHS release.
