BQ735 Overview
The bq24735 device is a high-efficiency, synchronous battery charger, offering low ponent count for space-constrained, multichemistry battery charging applications. The bq24735 device supports turbo boost by allowing battery discharge energy to the system when system power demand is temporarily higher than the adapter maximum power level so the adapter will not crash. The bq24735 device uses two charge pumps to...
