Energy Harvest

Energy Harvesting ICs are designed to capture and manage energy from ambient sources such as indoor light, solar cells, thermoelectric generators (TEGs), and other low-power energy sources, enabling battery-assisted or battery-free electronic systems. By integrating energy harvesting, battery management, DC/DC conversion, and intelligent power control into a single Power Management IC (PMIC), these solutions maximize energy utilization while reducing maintenance requirements. Advanced Energy Harvest PMICs feature ultra-low cold-start voltage, Maximum Power Point Tracking (MPPT), low quiescent current, and highly efficient power conversion to ensure reliable operation even under limited energy conditions. They are widely used in IoT sensors, wireless monitoring systems, smart metering, wearable electronics, industrial automation, and remote environmental monitoring. Energy Harvesting Power Management ICs help extend battery life, support maintenance-free designs, and provide a sustainable power solution for next-generation low-power electronic applications. ETEK's energy harvesting devices support cold-start operation from inputs as low as 275 mV, integrate battery management and high-efficiency buck/boost conversion, and are optimized for photovoltaic cells and TEG energy sources.
