Preliminary

Energy Harvesting with the EnerChip CC

The EnerChip CC can be configured to collect energy from transducers such as low power photovoltaic (PV)

cells and use that harvested energy to charge the integrated EnerChip and deliver self-sustaining power to

components such as microcontrollers, sensors, and radios in wireless systems. The schematic of Figure 8

illustrates the feedback connection made from RESET to EN to implement the energy harvesting function with

a CBC3112. In order to make most efficient use of the power available from the transducer (for example, a

PV cell), it is necessary to know the electrical characteristics including voltage and peak power point of the

transducer being used. For assistance in designing your system to effectively harvest energy from a power

transducer in a specific environment, contact Cymbet Applications Engineering.
