The REH-3.31.8 is dual output energy harvester module designed primarily for photo voltaic (PV) cells, but capable of running from other low voltage DC supplies delivering 50mV or more. This unique and compact (12.19 x 12.19 mm) module contains all the circuitry required to run a low power energy harvesting system, including a Maximum Power Point (MPP) tracking function for the PV cell. The user needs only to add the storage element (user selectable rechargeable battery or super capacitor) and connect the source to make it operational. Two short-circuit protected fixed voltage regulated outputs (1.8V and 3.3V) can be individually enabled/disabled. An imminent shutdown signal warns the application that there is not sufficient energy being harvested to maintain the output voltage and the module is about to power down. After start-up, the harvested energy will be stored on the storage device until the Vready voltage is reached, then the regulated outputs (if enabled) will be switched on, powered from the storage element.
