Inductorless energy harvesting PMIC with battery protection, LDO and USB charging

The NEH7110 is a high-performance power management IC (PMIC) for energy harvesting solutions in low-power applications. It has a rich set of auxiliary features, such as storage element protection, USB charging and LDO / load switch.

The NEH7110 is optimized to harvest energy from light sources (from a wide range of indoor and outdoor PV cells). Other energy sources can also be used, such as kinetic (movement, vibrations), thermal variation and electromagnetic, but might need external auxiliary components. The NEH7110 gathers energy from a suitable harvester to charge a storage element, such as a rechargeable battery or a supercapacitor.

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 frequent as every second for excellent performance in rapidly changing harvesting conditions.

The NEH7110 is available in 28-lead, 4 mm x 4 mm HVQFN28 package.

交互式数据手册

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
