Nexperia NEH2000BY Energy Harvesting PMIC
Energy harvesting technology, powered by Nowi technology,
has emerged as the means in which many power-related
problems facing the IoT may be solved. The energy fromincident light, vibrations, RF signals can be leveraged resulting in devices being able to run indefinitely without
the need for battery substitutions.

The NEH2000BY includes pre-sets on the chip, 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 harvestingin new product designs.

When energy harvesting is used, less room is needed for theenergy storage resulting in device miniaturization and BOM
reduction. IoT and low-power wireless devices can continue
to operate indefinitely, eliminating the need replace batteries
when they run out. Expanding battery life through energy
harvesting positively impacts the environment by reducing
battery waste and lowering the volume of raw materials
used in battery production.
Energy harvesting is often perceived as difficult due to thelevel of customization required per application and manydecisions 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 NEH2000BY PMIC changes
this entirely. The unique design require a minimum numberof external components, making the PCB design process
straightforward.

Nexperia’s advanced Maximum Power Point Tracking (MPPT)
uses an embedded hill-climbing algorithm to deliver themaximum power to the load. The MPPT is designed to be
independent of specific characteristics of the harvesters,
therefore any harvester that fits the specifications of thechip can be used. Moreover, the MPPT circuit can detect
the maximum power point with an interval of 0.7 second
resulting in maximum efficiency in various environments
where energy can rapidly change over time. The 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.
The NEH2000BY is available in a 16-lead, 3 mm × 3 mm
QFN package.

Innovative Power and Energy
Nexperia’s energy harvesting PMIC removes the needfor battery swaps, allowing for more sustainable productdesigns. NEH2000BY combines the lowest BOM cost withthe smallest PCB footprint and the best average harvesting
performance with an industry-fast maximum Power Point
Tracking (MPPT) of under 1 second. Key features of theNEH2000BY include unique inductor-less technology which
implies a minimum need for external components, conversion
efficiency of up to 80%, up to 2x Voltage boosting. Powerrange of 54 μW at 600 lux with AM-1454 PV, and Energy:
1.3 mWh per day at 600 lux for 8 hours with AM-1454 PV.
