General description
NEH2000BY is a high-performance energy harvesting solution for low-power applications. The
NEH2000BY harvests energy generated by a photo-voltaic (PV) cell. The energy charges a
rechargeable battery.
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. 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 NEH2000BY is available in a Plastic 16 terminal Quad Flat package, 3 mm x 3 mm.
