Nexperia enhances Energy Harvesting portfolio with innovative PMIC reducing BOM cost

Nexperia is expanding its energy harvesting portfolio with the NEH71x0 power management IC (PMIC) family. This advanced PMIC line combines superior performance, cost-efficiency, and versatility, setting a new standard in sustainable design for low power applications. Unlike competing products, these devices eliminate the need for an external inductor, significantly reducing circuit board space and bill-of-materials (BOM) cost. It is available in a compact 4 mm x 4 mm QFN28 package. Applications include remote controls, key fobs, smart tags, asset trackers, occupancy sensors, environmental monitors, wearables, keyboards, tire pressure monitors, and any number of Internet of Things (IoT) applications.

These new PMICs represent a complete power management solution for energy harvesting: enabling engineers to extend battery life, recharge batteries or supercapacitors, and even eliminate batteries in certain designs, thanks to its cold start feature. With the NEH71x0 (NEH7100BU, NEH7110BU) PMICs, designers can choose from multiple ambient power sources such as light, kinetic/piezo or a temperature gradient. With an input power range from 15μW to 100mW, these high-performance energy harvesting ICs can convert energy with an efficiency of up to 95%. These devices include an on-chip maximum power point tracking (MPPT) adaptive algorithm to optimize the energy harvested, which adapts every 0.5 second, making the PMIC extremely responsive to changing environmental conditions (more info).
