SMBus-controlled multi-chemistry charge controller for embedded systems
The Texas Instruments BQ24770RUYR is a multi-function battery charge controller that communicates over an SMBus interface, supporting multi-chemistry cells including Li-ion and LiFePO4 chemistries.
28-WQFN package and thermal considerations
The tape-and-reel delivery (3,000-piece reel typical) supports automated pick-and-place for volume assembly. The SMBus interface reduces pin count versus a parallel-controlled charger, freeing GPIO on the host MCU.
