Nexperia has introduced the NEH71x0 power management IC (PMIC) family, enhancing its energy harvesting solutions with a focus on performance, cost-efficiency, and sustainability. Unlike competing products, these innovative PMICs eliminate the need for an external inductor, reducing circuit board space and bill-of-materials (BOM) costs. Available in a compact 4 mm x 4 mm QFN28 package, these devices are ideal for low-power applications such as remote controls, wearables, smart tags, asset trackers, IoT devices, and more.
The NEH71x0 PMICs provide a complete power management solution for energy harvesting, supporting applications like battery life extension, battery recharging, or even battery elimination in some designs. These devices offer high efficiency—up to 95%—and support multiple power sources, including light, kinetic, and temperature gradients, with an input power range from 15μW to 100mW. An integrated maximum power point tracking (MPPT) adaptive algorithm optimizes energy harvesting by adjusting every 0.5 seconds based on changing environmental conditions.
Additional features include protection for batteries and storage elements, such as over-voltage, low-voltage detection, and over-current protection, as well as a low dropout (LDO) regulator and USB charging to simplify designs and lower BOM costs. The NEH7100BU variant also offers I2C programmability and measurement readings for added flexibility.
“We’ve created a cost-effective, sustainable solution for energy harvesting with the NEH71x0 family,” said Simon van der Jagt, Energy Harvesting Product Group Leader at Nexperia. “This new PMIC helps customers reduce costs while extending battery life and minimizing the environmental impact of battery replacements.”
The NEH71x0 family expands on Nexperia’s energy harvesting product line, following the release of the NEH2000 PMIC, and marks a significant step forward in developing inductor-less solutions for energy harvesting.
