Analog Devices has introduced a power management unit (PMU) designed to enable faster and more efficient energy harvesting in energy-scarce IoT applications – the ADP509x.

Due to its unique circuit design, the ADP509x ranks among the most efficient energy-harvesting PMUs on the market, converting harvested power into a range of 16 μW to 100 mW, with operating losses of only sub-μW. The ADP509x also offers the fastest cold-start times available today. Devices that rely on energy harvesting often need to slowly accumulate enough energy before they can turn on in low-energy situations, which means that there is a long delay before the device starts detecting, processing, and transmitting. This can result in missed data collection, slow operation, and a poor user experience. The ADP509x PMU solves these problems through a multi-power path design, making startup faster and operation smoother.

Efficient Energy Harvesting for IoT Applications

能量采集对于实现完全自主的物联网解决方案至关重要。对于电池更换成本很高的应用，它可以显著节省成本。另外，许多新兴应用不支持电池更换，能量采集为这些应用的实现提供了可能性。在许多应用中，能量采集的一个主要障碍是来自环境的能量水平非常低（例如微光室内太阳能采集），而且周期性地完全没有能量。这就要求电源管理解决方案不仅能以非常少的能量实现满意的系统运行，而且能有效管理储能装置，以便在采集不到能量的时候满足能量需求。

We believe that the ADP509x is a big step toward enabling new autonomous IoT applications. We are working with other companies, such as Alta Devices, which makes very innovative and efficient solar cells, to explore new possibilities by combining the most efficient energy harvesting devices. This will not only bring huge benefits to traditional IoT applications, but will also greatly simplify the implementation of emerging applications such as e-textiles and other wearable devices.
