BQ25570RGRR, Switching Battery Charger Li-Ion/Li-Pol/ Supercapacitor 110mA 2.2V to 5.5V 20-Pin VQFN EP T/R

bq25570 Power Management IC

Texas Instruments bq25570 Ultra Low Power Harvester Power Management IC is a highly integrated energy-harvesting Nano-Power management solution that is well suited for meeting the special needs of ultra low power applications. The product is specifically designed to efficiently acquire and manage the microwatts (µW) to milliwatts (mW) of power generated from a variety of DC sources like photovoltaic (solar) or thermal electric generators. The bq25570 is the first device of its kind to implement a highly efficient boost converter/charger with a nano-powered buck converter targeted toward products and systems, such as wireless sensor networks (WSN) which have stringent power and operational demands.
