ADVANCED LINEAR DEVICES, INC. e TM EPAD ENA ® B L E D EH300/EH300A/EH301/EH301A EH300/301 EPAD® ENERGY HARVESTINGTM MODULES GENERAL DESCRIPTION EH300/EH301 Series EPAD® Energy HarvestingTM Modules can accept energy from many types of electrical energy sources and store this energy to power conventional 3.3V and 5.0V electrical circuits and systems. EH300/EH301 Series modules are completely self-powered and always in the active mode. They are intended for low power intermittent duty cycle sampled data or condition-based monitoring/ extreme lifespan applications. These modules can accept instantaneous input voltages ranging from 0.0V to +/-500V AC or DC, and input currents from 200nA to 400mA from energy harvesting sources that produce electrical energy in either a steady or an intermittent and irregular manner with varying source impedances. EH300/EH301 Series modules condition the stored energy to provide power at output voltage and current levels that are within the limits of a particular electronic system power supply specifications. For example, 1.8V and 3.6V is a useful voltage range for many types of IC circuits, such as microprocessors. EH300/EH301 Series modules are designed to continuously and actively operate to capture, accumulate, and conserve energy from an external energy source. Each individual EH300/EH301 Series module is set to operate between two supply voltage thresholds, +V_low DC and +V_high DC, corresponding to the minimum (VL) and maximum (VH) s...
