NH2D0245 Image

The NH2D0245 from Nowi is an Energy Harvesting Power Management IC that is designed to harvest and deliver the extracted energy for low-power applications. It requires an input voltage of 2.5 - 4.5 V. This PMIC is an energy harvesting solution that harvests the energy generated by a source such as a photo-voltaic (PV) cell, or a piezo-electric harvester with a rectifier and uses this energy to charge a storage element such as a rechargeable battery or a supercapacitor. This PMIC embeds a hill-climbing algorithm on the advanced maximum power point tracking (MPPT) circuit that results in maximum power being delivered to the load. The MPPT integrated into the device is independent of specific characteristics of the harvesters and thus, any harvester that fits the specifications of the chip can be used.

The NH2D0245 is optimized in design to ensure a low Bill of Materials (BOM) and does not require any external coil to be connected. This PMIC is available in a surface-mount package that measures 3 x 3 mm and is ideal for wireless IoT devices, smart remote controls, beacons, wearable devices, electronic shelf labels, industrial and environmental monitoring, and consumer electronic applications.
