Nexperia's latest PMICs simplify and enhance the performance of low-power IoT and other embedded applications.
Nexperia has expanded its range of Power ICs with Energy Harvesting solutions to simplify and enhance the performance of low-power Internet of Things (IoT) and other embedded applications.
The NEH2000BY is a high-performance power management integrated circuit (PMIC) that recharges a battery or storage capacitor using energy harvested from ambient sources, such as light (which can be harvested using a photovoltaic cell). As a result, Nexperia’s NEH2000BY will enable the development of electronic devices that are self-powered, smaller, and environmentally friendly. Furthermore, this energy harvesting solution can help mitigate the environmental impact of the billions of batteries produced and discarded each year.
Nexperia’s NEH2000BY PMIC makes it much easier to design energy harvesting solutions which can be up to 20x smaller than other competing offerings and do not require manual optimization for individual applications. In addition, the PMIC was designed without inductors, simplifying PCB design, and significantly reducing overall BOM and board size, with a 12mm² assembly area.
为了达到最高的转化效率，能源收集溶液必须能够适应环境能源波动。NEH2000BY执行最大功率点跟踪（MPPT），这是一种自适应算法，以优化其如何传输收获能量并实现最佳平均转化效率高达80％。这种独特的MPPT算法将速度与精度相结合，使PMIC可以在不到一秒钟的时间内适应环境变化。这比当前可用的任何其他解决方案都要快得多，并最大程度地提高了一天中收获的能量量，从而大大扩大了应用领域的数量。此外，由于其自我优化功能和自主操作的能力而无需进行预先编程的要求，NEH2000BOBY使设计人员更容易为具有环境能量的设备供电。
Nexperia’s energy harvesting solutions enable economical energy harvesting from various ambient sources in applications consuming up to several milliwatts of power, including wireless 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.
NEH2000BY有16铅，3 mm×3 mm QFN包装，可在-40°C和 +85°C之间使用。
