Easy to use energy harvesting PMIC

This device harvests energy generated by a photovoltaic (PV) cell, which in turn charges a rechargeable battery.

It is an ideal choice for low-power applications, including wireless Internet of Things (IoT) devices, wearable devices, smart remote controls, and industrial and environmental monitoring.

The PMIC includes pre-sets on the chip, making the implementation of energy harvesting designs 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.

Nexperia’s advanced maximum power point tracking (MPPT) uses an embedded hill-climbing algorithm to deliver the maximum 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 the chip can be used.

In addition, the MPPT circuit can detect the maximum power point with an interval of 0.7 seconds resulting in maximum efficiency in various environments where energy can rapidly change over time.

The MPPT functions autonomously and requires no pre-programming.

Consequently, self-optimisation makes it no longer required to have an extremely detailed understanding of the fluctuating environment.

The NEH2000BYJ PMIC offers a harvesting power range from 35 μW to 2 mW and is available in a compact, 16-lead 3.0 mm × 3.0 mm QFN package, ideal for space-constrained applications.
