Multi-chemistry SMBus charger controller for portable power designs
The Texas Instruments BQ24770RUYT is a multi-function controller that manages battery charging across multiple chemistries — Li-Ion, Li-Po, NiMH — through an SMBus interface. It handles charge current and voltage regulation, adapter current limiting, and system power-path management in a single 28-WQFN package.
Package options and footprint reality
The BQ24770RUYT is supplied in Tape & Reel (TR) for automated assembly or Cut Tape (CT) for prototype/low-volume builds.
No official successor or replacement has been issued, so the base product number BQ24770 remains the current design-in target.
