NEH7110BUHP

NEH7110 is a high-performance energy harvesting power management IC designed for low-power applications, integrating a rich set of auxiliary features including storage element protection, USB charging, and LDO/load switch. The device is optimized for harvesting energy from light sources — covering a wide range of indoor and outdoor photovoltaic cells — while also being compatible with other energy sources such as kinetic (motion, vibration), thermoelectric, and electromagnetic energy, though external auxiliary components may be required. The NEH7110 harvests energy from a suitable harvester to charge storage elements such as rechargeable batteries or supercapacitors. Its built-in maximum power point tracking employs an embedded hill-climbing algorithm to deliver maximum power to the storage element. This MPPT function is compatible with any suitable harvester and can optimize efficiency at rates of up to once per second, enabling excellent performance under rapidly changing harvesting conditions. The NEH7110 is available in a 28-pin, 4 mm × 4 mm HVQFN28 package.
