GENERAL DESCRIPTION
BENEFITS
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 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 +/-500VAC or DC, and input currents from 200nAto 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.
• Eliminates manual and elaborate
system trimming procedures
• Remote controlled automated trimming
• In-System Programming capability
• No external components
• No internal clocking noise source
APPLICATIONS
• Sensor interface circuits
• Transducer biasing circuits
• Capacitive and charge integration circuits
• Biochemical probe interface
• Signal conditioning
• Portable instruments
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
MECHANICAL SPECIFICATIONS
and maximum (V ) supply voltage values for the intended appli-
H
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.

FUNCTIONAL DESCRIPTION
ENVIRONMENTAL SPECIFICATIONS
The EH300/EH301 Series module's voltage on the onboard
storage capacitor bank is +V, which is also the positive sup-
ply voltage switched to power the output power load. Ini-
tially, +V voltage on an EH300/EH301 Series module starts
at 0.0V. During the initial charge period, +V starts charging
from 0.0V. The module's internal circuit monitors and de-

• Operating Temperature Range: 0 to 70° C

then able to supply power to a power load, such as a micro-
processor and/or a sensor circuit. The amount of useful en-
ergy available is a function of the capacity of the storage
capacitor bank. Meanwhile, an EH300/EH301 Series mod-
ule continues to accumulate any energy generated by ex-
ternal energy sources. If external energy input availability is
INITIAL SETUP & CALIBRATION
EH300/EH301 Series modules are setup and calibrated
at the factory to standard specifications and settings.
No user setup is required. Optional user control signal
and connection to external capacitor or battery storage
banks are available at the output port. All EH300/EH301
Series modules are shipped ready to use.
high, output V remains in an ON state continuously, until

such time that external energy availability is lower than the
power demand required by the power load. As external en-
ergy input exceeds power loading, +V increases until inter-
nal voltage clamp circuits limit it to a maximum clamp volt-
age.
EH300/EH301 Waveforms
During normal operation, as power is drawn from an EH300/
EH301 Series module, +V decreases in voltage. When +V

Input energy charging times t1 and t2 are limited by input
energy available minus energy loss by an EH300/EH301
Series module. The energy output time period t3 is deter-
mined by the rate of energy used by the power load as a
function of energy stored. Low input energy hold time t4 is
typically many orders of magnitude greater than the sum of
t1, t2 and t3.
