Product details

Charger IC for 2-4 cell Li-Ion packs, 8A programmable current

The Texas Instruments BQ24704RGER is a constant-current, constant-voltage Li-Ion/Polymer battery charger controller supporting 2 to 4 series cells with a maximum charge current of 8A. Operating from a supply up to 24V, it integrates over-current, over-temperature, and over-voltage fault protection, reducing external monitoring circuitry.

8A charge current and cell-count flexibility

The programmable charge current up to 8A allows the BQ24704RGER to charge large-capacity battery packs in notebooks, power tools, and portable equipment without an external current-sense amplifier. Supporting 2 to 4 cells, the charger adapts to battery pack voltages from ~7.2V up to 18V maximum, covering the majority of multi-cell Li-Ion configurations.

Frequently asked questions

Is BQ24704RGER compatible with 4-cell batteries?

Yes, the BQ24704RGER supports 2 to 4 series cells, with a maximum battery pack voltage of 18V, making it compatible with 4-cell Li-Ion packs.
