Product details

10A multi-chemistry charger for 2-4 cell packs

The 24V max supply voltage covers the typical adapter rail for these applications.

The 10A max charge current is the headline number — it sets the MOSFET Rds(on) budget, inductor saturation current, and PCB copper pour for the charger's buck converter stage. The 24V supply ceiling means the input adapter can be a standard 19V notebook brick with margin for transients. Over-current and over-voltage fault protection are integrated, so the external protection circuit can be minimal — just the input fuse and output cap.

Surface mount only; the Tape & Reel (TR) packaging suits automated pick-and-place.

Frequently asked questions

Is BQ24751ARHDT compatible with 2-cell Li-ion batteries?

Yes, the BQ24751ARHDT supports 2 to 4 series cells, so a 2-cell Li-ion pack (typical 7.4V nominal, 8.4V full charge) is within its operating range. The battery pack voltage limit is 18.04V max.

Where can I find the BQ24751ARHDT datasheet?

The datasheet for BQ24751ARHDT is available from Texas Instruments under the base product number BQ24751. It contains the full electrical characteristics, application schematic, and layout guidelines for the 10A charger design.
