Key Benefits
Simple
Energy harvesting is often perceived as difficult due to the level of customization required per application and many decisions application engineers are required to make in their PCB design process. In practice, this has acted as a barrier for implementation of energy harvesting technology.
Nexperia’s Energy Harvesting PMIC portfolio changes this entirely. The unique design require a minimum number of external components, making the PCB design process straightforward.

The Maximum Power Point Tracking (MPPT) functions autonomously and requires no pre-programming. Consequently, the self-optimization makes it no longer required to have an extremely detailed understanding of the fluctuating environment.
Our engineering team has also developed predefined configurations with pre-sets on a selection of chips, making the implementation of the chip simpler. This offers an unprecedented ease-of-use for engineers. Even with limited energy harvesting knowledge, it is possible to quickly integrate and deploy high performing energy harvesting in new product designs.

Ultra Small
PCB area is a rare resource in many products and for that reason, energy harvesting has historically been problematic to implement in numerous product categories. Traditional solutions have required 150-300mm2 area due to their large assembly Bill of Material (BOM) of up to 15 external components. From wearable devices to sensor tags, this area is often simply not available and made energy harvesting implementation difficult.
Nexperia’s innovative design for its energy harvesting power management ICs reduces the BOM to a few small external capacitors, and as a result, the assembly area has been minimized to a maximum of 20mm2.

For the first time, top energy harvesting performance is able to fit in just about any sized product.
In a green and connected future, Nexperia views energy harvesting technology as an essential and standard feature in most devices. Long term cost and ease-of-use features can be maximized by an increased integration, making size all the more important. Nexperia Energy Harvesting Solutions can be integrated into larger SoCs or modules thanks to its compact size, allowing to reduce the area footprint of energy harvesting in smart products.

Cost-Efficient
Nexperia believes that connecting the physical world to the digital world will offer tremendous societal benefits, however, on this scale, costs become key. Just as swapping batteries at a big scale is economically unfeasible, so is having a large BOM for each product. Traditionally, energy harvesting has been expensive to implement, given the inductor-based designs of existing PMICs and an addition of 10-15 external components to function.
Our energy harvesting power management is based on an entirely different design which greatly reduces the required assembly BOM to just a few external capacitors, limiting the PMIC implementation cost and removing the need for costly inductors.

A selection of our chipsets offers power management features, making Nexperia Energy Harvesting PMICs such as Diatom “all-in-one” complete solutions that remove the need for additional power management ICs.
Besides advantages in size and simplicity, this offers large cost savings per product. The assembly BOM is reduced from $0,50-0,70 to less than 1 cent, making our PMICs attractive for existing energy harvesting applications, as well as for new cost-constrained use cases.

Top Performance
Nexperia Energy Harvesting PMICs are high-performance energy harvesting solutions for low-power applications designed to work efficiently in the range of microwatts (μW) to milliwatts (mW) of power. Our chipsets are designed to extract the power output of a wide range of energy harvesters to charge a variety of energy storage elements.
The speed of the Maximum Power Point Tracking (MPPT) of Nowi technology is key in achieving optimal average efficiency. As the source of power fluctuates, the PMIC needs to adapt in order to achieve the highest conversion efficiency. As a result, the amount of energy that is ‘harvested’ per day is mostly driven by how fast the PMIC is able to find the best configuration in which it can convert the most amount of power.

This unique MPPT combines speed with accuracy and can adapt within 0,5 second to a change in the environment, which is significantly faster than any other solution available in the market and maximizes the energy harvested throughout a day, thereby vastly expanding application areas.
