What this multi-chemistry charger IC does
The BQ24700PW is a multi-chemistry battery charger controller from Texas Instruments, designed to handle Li-Ion, NiMH, NiCd, and other chemistries with a single charge algorithm.
Package and board-fit for hand assembly
The supplier device package is 24-TSSOP, and it ships in a tube (not tape-and-reel), so you'll get a handful of ICs in a single tube — handy for prototyping or small runs.
