DESCRIPTION  
The bq25504 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. The bq25504 is  
the first device of its kind to implement a highly efficient boost converter/charger targeted toward products and  
systems, such as wireless sensor networks (WSN) which have stringent power and operational demands. The  
design of the bq25504 starts with a DCDC boost converter/charger that requires only microwatts of power to  
begin operating.
