DESCRIPTION  
The bq25505 is the first of a new family of intelligent integrated energy harvesting Nano-Power management  
solutions that are 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 miliwatts (mW) of power  
generated from a variety of DC sources like photovoltaic (solar) or thermal electric generators (TEGs). The  
bq25505 is a highly efficient boost charger targeted toward products and systems, such as wireless sensor  
networks (WSN) which have stringent power and operational demands. The design of the bq25505 starts with a  
DCDC boost charger that requires only microwatts of power to begin operating.
