![]() The BQ25504 also implements a programmable maximum power point tracking sampling network to optimize the transfer of power into the device. The boost converter can be started with V IN as low as 600 mV, and once started, can continue to harvest energy down to V IN = 130 mV. Once started, the boost converter/charger can effectively extract power from low-voltage output harvesters such as thermoelectric generators (TEGs) or single- or dual-cell solar panels. The design of the BQ25504 starts with a DC-DC boost converter/charger that requires only microwatts of power to begin operating. 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 (WSNs) which have stringent power and operational demands. ![]() ![]() The device 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 device 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.
