    Maximum efficiency in the process of capturing solar energy, enabling reduced charging time and enhancing greater user freedom.

    The microchip EH01 (Energy Harvesting 01), aims to manage the process of capturing energy for off-grid electronic devices, providing maximum efficiency in the process of capturing solar energy, thus enabling reduced charging times and enhancing user freedom.

    The EH01 is a complete power management solution for a variety of energy-harvesting applications, providing a small and simple solution to obtain power from three different sources: a wall adapter, photovoltaic cells and a Li-Ion battery. This device then enables the implementation of USB chargers following the ITU standard for the Universal Charging Solution (L.1000).

    The device contains one high efficiency DC/DC converter, a fully-featured Li-Ion Battery Charger, and numerous protection features. The EH01 also provides two outputs for battery status monitoring. One indicates if the battery is charging (when using a solar panel or a wall adapter as input), whereas the other one gives an estimate of the battery charge level. The EH01 is a simple solution to obtain maximum power from three different sources:

    • Conventional power grid,
    • Solar cells and
    • Li-Ion Battery
    • 1LOW POWER
      • Consumption less than 500 uW in standby mode.
    • 2VOLTAGE CONTROLLED CONVERTER
    • 3USB OUTPUT ADHERENT WITH L.1000 RECOMMENDATION (UNIVERSAL CHARGING SOLUTION)
      • Serves a wider range of portable devices.
    • 4INPUT VOLTAGE FROM 3V TO 5.5V
    • 5WORKS BOTH WITH GRID AND SOLAR CELLS
      • More autonomy, flexibility and mobility.
    • 6AN SINGLE CHIP SOLUTION
      • Size reduction of printed circuit boards and shorter time in assembly line (pick-and-place);
      • Gains in miniaturization;
      • Cost reduction (Reduced BoM);
      • No need for other generic components, such as external regulators and converters.
