Nexperia NEH71x0 Inductorless Energy Harvesting PMICs
Nexperia NEH71x0 Inductorless Energy Harvesting Power Management Integrated Circuits (PMICs) are high-performance devices for energy harvesting solutions in low-power applications. The Nexperia NEH7100 and NEH7110 PMICs offer a rich set of auxiliary features, such as storage element protection, USB charging, and low dropout (LDO). These devices are optimized to harvest energy from a wide range of sources, such as light (indoor/outdoor PV cells), kinetic (movement/vibrations), thermal variation, and electromagnetic. The NEH71x0 PMICs gather energy from a suitable harvester to charge a storage element, such as a rechargeable battery or a supercapacitor. These components are available in a 28-lead, 4mm x 4mm x QFN package.Nexperia's advanced maximum power point tracking (MPPT) uses an embedded hill-climbing algorithm to deliver maximum power to the storage element. The MPPT is compatible with any suitable harvester and optimizes efficiency as frequently as every 0.5 seconds for excellent performance in rapidly changing harvesting conditions.
