Overview for Energy Harvesting & Solar Charging

Industry’s most efficient nano power harvesting solutions




Energy harvesting with breakthrough TI technology allows the development of systems that extract and manage nano power from a variety of sources such as solar, thermal electric, electromagnetic, and vibration energy. From solar-powered sensors for wireless monitoring of factories or farms to using body heat to power sensors on medical and fitness equipment, TI and leading energy harvesting partners are creating a complete ecosystem for designers to envision and create a battery-less world.

From low power to no power, TI delivers the most efficient energy harvesters:

  • Low quiescent currents (350 na typical)
  • >90% conversion efficiency even at currents as low as 15 µA
  • User-programmable devices with Maximum Power Point Tracking (MPPT) for optimized extraction
  • Cold start capability for very low input conditions
