AEM10940 – Photovoltaic Energy Harvesting Power Management IC


E-peas’ photovoltaic energy harvesting IC solution – AEM10940 – is an integrated energy management subsystem that extracts DC power from up to 2 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, geolocation, home automation, wearables.

    Energy harvester AEM10941 e-peas

    The AEM10940 Evaluation Board is a printed circuit board (PCB) assembly featuring all needed components to put in operation the AEM10940 integrated circuit (IC) from e-peas. Please refer to the AEM10940 data sheet for all useful details about this IC.

    It allows you to test the component and analyze its performance in a laboratory-like environment. The AEM10940 Evaluation Board is not intended for final implementation in an end-user application.

    The board provides easy connections to the source of harvested energy, the storage element, the low voltage load and the high voltage load. It includes all the configuration items to set the device in any modes described in the data sheet. The control and status pins are available on standard pin headers, enabling wiring for any usage scenario and evaluation of the corresponding performance.

    The AEM10940 Evaluation Board is your indispensable tool to take appropriate decisions (component selection, operating modes…) regarding the design of a highly efficient energy harvester subsystem in your target application.
