The NEH2000BYJ from Nexperia is a High-Performance Energy Harvesting IC that is ideal for beacons, wireless IoT devices, smart remote controls, electronic shelf labels, wearable devices, consumer electronics, and industrial/environmental monitoring applications. It requires an input voltage of 1.65 V. This PMIC includes a low-power boosting DC-DC converter, maximum power point tracking (MPPT) block, battery supply functions, oscillator, and reference voltage capabilities. It harvests the energy generated by a photovoltaic (PV) cell and uses this energy to charge a rechargeable battery. This IC utilizes advanced MPPT technology that incorporates a hill-climbing algorithm to deliver maximum power to the load. It can detect maximum power points with an interval of 700 ms, thereby resulting in maximum efficiency in various environments where energy can rapidly change over time.

This energy harvesting IC has been designed to be independent of specific characteristics of the harvesters and therefore, any harvester that fits the specifications of the IC chip can be used. It also eliminates the use of external inductors within the chip, which reduces the bill of materials (BOM). This PMIC is available in a surface-mount package that measures 3 x 3 x 0.75 mm.
