Nexperia has launched its first energy harvesting power management IC (PMIC) following its acquisition of Nowi in Belgium in November 2022.

The NEH2000BY was formerly Nowi’s Codium NH2D0245 to simplify and enhance the performance of low-power internet of things (IoT) and other embedded applications. This is a key part of Nexperia’s move to broaden its product range with more complex power management devices.

The NEH2000BY recharges a battery or storage capacitor using energy harvested from ambient sources such as a solar cell. The PMIC allows designs without inductors, simplifying PCB layouts and significantly reducing the overall design cost and board size, with a 12 mm² assembly area. The device is available in a 16-lead, 3 mm × 3 mm QFN package and operates between -40 °C and +85 °C.

The NEH2000BY performs Maximum Power Point Tracking (MPPT), an adaptive algorithm to optimize how it transfers harvested energy and to achieve optimum average conversion efficiency by up to 80%. The MPPT algorithm combines speed with accuracy, allowing the PMIC to adapt to environmental changes in 0.7s. This is significantly faster than any other currently available energy harvesting PMIC says Nexperia.

Self-optimization and ability to operate autonomously without the requirement for pre-programming make it easier to operate, producing several milliwatts of power for ireless IoT nodes, wearable smart tags and electronic shelf labels.

“The NEH2000BY’s cost-efficient, user-friendly, and compact nature will allow the adoption of energy harvesting in a larger range of use cases. By eliminating the requirement to change batteries in these applications, NEH2000BY will significantly reduce the amount of hazardous waste produced, with enormous environmental benefits,” said Dan Jensen, General Manager Business Group Analog & Logic IC’s at Nexperia.
