AEM10941 – Energy Harvesting Power Management IC

Description

E-peas’ photovoltaic energy harvesting IC solution – AEM10941 – is the next generation integrated energy management subsystem that extracts DC power from up to 7 cells solar panels to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages. This allows product designers and engineers to extend battery lifetime and ultimately get rid of the primary energy storage element in a large range of wireless applications like industrial monitoring, home automation, wearables.Read More...
