GENERAL DESCRIPTION
EH300/EH301 Series EPAD
®
Energy Harvesting
TM
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 com-
pletely 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 vary-
ing 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 microproces-
sors.
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 (V
L
)
and maximum (V
H
) supply voltage values for the intended appli-
cation. When an energy source starts to inject energy into the
inputs of an EH300/EH301 Series module in the form of electrical
charge impulses, these charge packets are collected, accumulated
and stored onto an internal storage capacitor bank. For most com-
mon energy harvesting applications, the electrical energy charge
packets arrives in the form of input voltage spikes that are uncon-
trolled and unpredictable. Often these cover a wide range of volt-
ages, currents and timing waveforms. EH300/EH301 Series mod-
ules are designed to accommodate such conditions with excep-
tional efficiency and effectiveness
.
As an example, a EH300 mod-
ule can cycle within 4 minutes at an average input current of 10µA
and within 40 minutes at an average input current of just 1.0µA.
