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.
