bq24770 Overview
The bq2477x is high-efficiency, synchronous, NVDC1 battery charge controllers, offering low ponent count for space-constraint, multi-chemistry battery charging applications. The power path management allows the system to be regulated at battery voltage but does not drop below system minimum voltage (programmable).
