Complete low BoM PMIC with dual energy harvesting source inputs

The new energy harvesting IC AEM13920 from e-peas can handle simultaneous inputs from two independent harvested energy sources such as PV, RF, thermal and kinetic energy sources. For the usage of energy harvesting in small electronics devices like remote controls, PC peripherals, wireless sensors, and more, the flexible dual-source capability enables new design opportunities. Examples include: A remote control could have separate PV cells on its front and rear, to maintain an energy input whether the device is left face up or face down. A smart wireless light switch could operate on mechanical energy for short RF transmissions, and on stored mechanical or light energy for longer operations such as downloading and installing a firmware update. AEM13920 provides a complete power management solution with added new features for system optimization and protection. More than 90% source-to-storage and storage-to-load conversion efficiencies are achieved by the PMIC. The quantity of energy extracted from each type of harvester is maximized by using separate maximum power point tracking (MPPT) algorithms for each source and an extremely low cold-start input condition of 275 mV/5 W. Constant source-voltage regulation is another option available with the AEM13920. Since AEM13920 implements all the functionalities necessary to store and utilise energy from an extern...
