Product details

10 A charge current with multi-chemistry flexibility

The Texas Instruments BQ24751RHDR is a multi-chemistry battery charger IC that handles 2 to 4 series cells with a programmable constant-current charge up to 10 A max.

NRND — plan the last-time buy now

That means the part is still available for existing production runs, but TI will eventually issue an EOL notice with a last-time-buy window. If this is on your BOM, secure a lifetime buy quantity now — the LTB window is your only guaranteed path to fill the line without a redesign.

Fault protection and package details

Built-in over-current and over-voltage fault protection reduces external component count. The 28-VFQFN Exposed Pad package (5x5 mm) with a thermal pad demands a solid via array under the paddle to pull heat into the ground plane.

Frequently asked questions

What is the exact replacement for BQ24751RHDR?

A parametric search for a multi-chemistry charger IC with 2-4 cell support, 10 A max charge current, and 24 V supply max is the next step — expect a board layout change given the 28-VQFN footprint.

Can BQ24751RHDR charge 4 Li-ion cells?

Yes, the BQ24751RHDR supports 2 to 4 series cells, with a maximum battery pack voltage of 18.048 V. That covers a standard 4-cell Li-ion stack (4 × 4.2 V = 16.8 V) with headroom.

What is the difference between BQ24751RHDR and BQ24751RHDT?

The die and package are identical — no parametric difference. Choose the reel size that matches your pick-and-place feeder setup.
