Built-in over-current and over-voltage fault protection reduces external component count.
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.
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.
The die and package are identical — no parametric difference. Choose the reel size that matches your pick-and-place feeder setup.
