Choosing a Power Management IC for Energy-Harvesting Applications
The power-management IC (PMIC) supports and manages the transducer and energy-collection channel, the energy-storage element (battery, conventional capacitor or supercapacitor), and the processor/wireless link. This critical block of any energy-harvesting design implements several major functions: Captures and extracts the random, miniscule energy from the source transducer Transforms that extracted power into energy for the storage […]
