Nexperia Launches NEH2000BY Energy Harvesting Power ICs to Simplify and Enhance Performance of Low-Power IoT Applications

Category articles

 Nexperia is a leading manufacturer of fundamental semiconductors, has announced the expansion of its line of Power ICs with Energy Harvesting solutions that simplify and improve performances of lower-power Internet of things (IoT) and other embedded applications. The NEH2000BY, a high-performance integrated circuit for power management (PMIC) that recharges batteries or storage capacitors by utilizing energy from natural sources like light (which is able to be captured using photovoltaic cells). In the end, Nexperia’s NEH2000BY will allow the creation technology for electronic products that operate on their own smaller, lighter, and more green. In addition, this energy harvesting solution will help reduce negative environmental impacts of millions of batteries that are produced and then disposed every year.
An integrated circuit for power management (PMIC) is one form that is an integrated circuit (IC) that controls the power demands of an entire system. It regulates how much power is supplied to different elements of a system, and ensure that they are supplied with the necessary voltage as well as current and power. PMICs are used to regulate power supply to various components of a system. PMIC generally comprises the following components: voltage regulators, current regulators and power switches. They could also contain features like power sequencers, monitoring power as well as thermal control. PMICs are often found in portable devices including tablets, smartphones or laptops as as other electronic systems like routers, servers or industrial machines.

Nexperia’s NEH2000BY PMIC helps make it simpler to design energy harvesting systems that can be as much as 20x smaller than the other offerings and don’t need manual adjustments for individual applications. Additionally to that, the PMIC was created without the use of inductors, which makes PCB design simpler and drastically decreasing overall BOM and board sizes with a 12mm2 assembly area.

In order to achieve the best effectiveness of conversions, all energy harvesting systems have to be able of adjusting to the changing energy sources as the environment changes. The NEH2000BY uses Max Power Point Tracking (MPPT) that is an adaptive algorithm designed to optimize the way it is able to transfer energy, and to maximize efficiency in conversion, ranging from 80% to 80 percent. This exclusive MPPT algorithm combines speed and precision and allows the PMIC to respond to changes in the environment within less than 1 second. This is significantly faster than alternative currently available and increases how much energy that is gathered throughout the day, greatly expanding the range of applications. In addition, thanks to its self-optimization capabilities and the capability to operate autonomously, without the need for pre-programming the NEH2000BY makes it simpler for designers to run devices using energy from the environment.

Nexperia’s energy harvesting products allow efficient energy harvesting from a variety of sources of energy in applications that consume many milliwatts of energy such as wireless IoT nodes and wearable smart tags as well as electronic labels for shelves.

Dan Jensen, General Manager Business Group Analog and Logical IC’s at Nexperia says “The NEH2000BY’s low-cost, user-friendly and compact design will enable the use of energy harvesting across more diverse use applications. In removing the need to replace batteries in these scenarios, NEH2000BY will significantly reduce the quantity of hazardous waste generated as well as provide significant environmental benefits.”

The NEH2000BY comes in a 16-lead and 3 mm x 3mm QFN packaging and is able to operate between -40degC to +85degC.
