EH300, EH301 EH circuit
The EH300/EH301 Series EH Modules from Advanced Linear Devices can accept energy from many types of electrical energy sources and store this energy to power conventional 3.3V and 5.0V electrical circuits. EH300/EH301 Series Modules are completely selfpowered and always in the active mode. They can function with instantaneous input voltages ranging from 0.0V to +/-500V AC or DC, and input currents from 200nA to 400mA.
Harvested energy can be collected from sources that produce electrical energy in either a steady or an intermittent and irregular manner with varying source impedances.
