The BQ24703PW is a multi-chemistry battery charge controller from Texas Instruments, designed to handle Li-ion, Li-Po, NiMH, and lead-acid packs from a single IC — no need to swap the BOM when the chemistry changes.
Package and mounting — hand-solderable TSSOP
The 24-TSSOP package (0.173" body width, 4.40 mm pitch) is a common footprint that can be hand-soldered with a fine-tip iron and flux — no hot-air station required, though a stencil helps for production. It ships in a Tube, which is convenient for prototyping and low-volume builds; the reeled variant (BQ24703PWR) is also available for automated assembly.
