PMIC

Nexperia has launched NEH2000BY, a high-performance power management integrated circuit (PMIC), to simplify and enhance the performance of low-power applications, including Internet of Things (IoT) devices and embedded systems. The company claims the PMIC is designed to recharge batteries or storage capacitors using harvested energy from surrounding sources, such as ambient light harnessed through photovoltaic cells. This energy harvesting solution also holds the potential to curb the environmental impact caused by the enormous number of batteries produced and discarded annually. The PMIC revolutionises energy harvesting solutions, offering a remarkable advantage over competing offerings by allowing designs up to 20 times smaller without manual optimisation for specific applications. 

The PMIC sets itself apart by ingeniously omitting inductors, resulting in simplified PCB design and significant reductions in an overall bill of materials (BOM) and board size, all fitting within a compact 12 mm² assembly area. The PMIC achieves high conversion efficiency by employing adaptive Maximum Power Point Tracking (MPPT), optimising energy transfer with up to 80% efficiency. Its unique algorithm quickly adapts to environmental changes, maximising energy harvest. It simplifies design and operates autonomously, expanding application areas. The energy harvesting solutions cater to applications that consume up to several milliwatts of power, including wireless IoT nodes, wearable smart tags, and electronic shelf labels, enabling economical energy harvesting from various ambient sources. This technology empowers the development of energy-efficient, eco-friendly electronic devices across diverse industries.

Dan Jensen, General Manager Business Group Analog & Logic ICs at Nexperia, adds, “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.”
