Nowi BV (Delft, The Netherlands) has samples available of its NH2 energy harvesting power management IC (PMIC).The NH2D0245 comes in a QFN package measuring 3mm by 3mm. Including the external capacitor, it has an assembly footprint of just 3mm by 3.6mm. The NH2 is designed to extract the low power output of an energy harvesting source to charge a variety of energy storage elements such as a rechargeable battery or a super-capacitor. It is optimized for Solar PV (indoor and outdoor).
