General Description
The INFINERGY™ Development Micro Power Module
(D-MPM101) from Infinite Power Solutions (IPS) is an inte-
grated micro power storage and regulation device intended
to efficiently store harvested micro energy produced by
ambient energy harvesting transducers. It serves applica-
tions requiring a well regulated, deeply embedded energy
storage device and power supply. The D-MPM101 has con-
nectors to facilitate system-level prototyping. It can store
energy from poorly regulated sources such as energy har-
vesting devices with output power levels ranging from less
than 1 µW to 100 mW or more, with retention periods of up
to ten years. Single or multiple THINERGY™ micro energy
cells (MECs) are included with the D-MPM101 to supply up
to 2 mAh of energy storage from a single unit, allowing
semi-active embedded devices such as wireless sensors to
transmit megabits of information on a single charge. Output
voltages supplied to the target applications are regulated
using efficient fixed LDO (Low Drop Out) linear regulators
with available common voltage levels required by all mod-
ern embedded devices from 2.1V to 3.6V.

INFINERGY™ D-MPM101: Integrated Solid-State Micro-Power Storage Module
Charge acceptance from most energy harvesting devices
utilizing mechanical/vibration, photovoltaic, thermo-electric,
RF and other energy sources is highly efficient and gener-
ally does not require additional external interface
components such as bridges or diodes. The MECs inte-
grated onto the D-MPM101 are completely managed by the
D-MPM101 electronics which monitor input charge regula-
tion while providing output regulation and under-voltage
protection. When combined with energy harvesting devices,
applications such as wireless sensor modules can be pow-
ered with the D-MPM101 for many years, providing
maintenance-free energy storage and power for the
intended life of the application.

INFINERGY™ D-MPM101: Integrated Solid-State Micro-Power Storage Module
Typical Configuration
Figure 2 shows a typical D-MPM101 configuration as it
would be used in a wireless sensor node application. Note
that the enable pins for the output regulator are connected
to switches that disable the outputs of the onboard LDO
regulator whenever the host application is not in an active
state.
By disconnecting the host application completely from the
application load, the device can be placed into an
"Off/Active" state. The device can be wakened by applying
a small amount of energy produced from an external sen-
sor or event such as a radio frequency pulse or impulse
from a piezoelectric device or sensor which will initially
provide enough energy to momentarily activate the
D-MPM101, subsequently activating the host application
to service the event. Off/Active operation is a recom-
mended method for operating intermittently active wireless
sensor nodes. By completely disconnecting the power
source from the application and utilizing the energy from
the sensors or input devices provided by the sensor or
application to trigger the wakeup operation, the application
can be sustained in an inactive state for periods of time
exceeding five years.
In cases where a watchdog timer, memory backup, or Real
Time Clock (RTC) circuit is required to support the applica-
tion, direct connection to the MEC at J1 can be made.
Care must be taken to ensure that the drain rate of the
attached load is sufficiently low that the MEC will not be
completely discharged before the next recharge period
begins, or permanent failure of the D-MPM101 will occur.
Please contact IPS for support with Off/Active operation.
Detailed Description
MEC Configuration
The D-MPM101 has the capability to support multiple
MECs (Micro Energy Cells) electrically connected in a par-
allel configuration in order to increase the effective
capacity of the D-MPM101. Currently available configura-
tions include one or two MEC devices. MECs are available
in two capacity ratings for the D-MPM101: 700 µAh and
1.0 mAh (Ah = Ampere Hour). D-MPM101s with two cell
configurations would therefore be available in 1.4 mAh and
2.0 mAh versions. D-MPM101s are not available with
mixed values, e.g. 1.7 mAh.
In addition to increasing capacity, adding additional MECs
to the D-MPM101 devices also increases the peak output
power. Therefore, the D-MPM101-14, a D-MPM101 ver-
sion with two 700 µAh MECs, would provide twice the
output power (twice the current).
Figure 3 shows the relationship between the peak power
and capacity of the single and dual MEC options available
on the D-MPM101. Additional MECs in excess of the
MECs soldered to the underside of the D-MPM101 can be
added in parallel to increase the capacity of the D-
MPM101 by connecting them through the direct connec-
tion found at J1.

Under-Voltage Protection
Integrated under-voltage protection is provided by the
D-MPM101 and is transparent to the application being
powered. The D-MPM101 will automatically shut off the
regulated output in any case where the integrated MEC
voltage falls below 2.1V, the lower acceptable discharge
limit of an IPS MEC. When the MEC is discharged below
the 2.1V under-voltage limit, the D-MPM101 will latch the
output to an open output state until 4.1V or more is applied
to the AC or DC charge input terminals and MEC capacity
rises above 20%.
Figure 4 describes the timing for the under-voltage output
cutoff.
As shown in Figure 4, the regulated output VREG OUT and
the isolated return line 2.1 RTN are deactivated when the
MEC is discharged below the discharge cutoff threshold of
2.1V, completely isolating the application circuit from the
regulated output voltage. This reduces leakage current,
protecting the MEC from situations where a full discharge

of the MEC occurs and then is followed by a long stand
period without recharge being provided. If the MEC is not
isolated from the load following a deep discharge, high
leakage currents will cause the MEC to be permanently
discharged below the 2.1V threshold, causing permanent
damage to the MEC. Using the 2.1 RTN line isolation as
the ground or return line to the D-MPM101 from the appli-
cation will isolate the MEC completely from the application
and the internal D-MPM101 regulator, allowing the
D-MPM101 to remain in a discharged state for extended
periods of time—from months to years—without recharge
energy being required. The output LDO regulator is also
disconnected from the MEC in this case, removing the qui-
escent current drain from the MEC while the D-MPM101
waits for recharge energy.
Upon receipt of charge energy into the MEC that
recharges the MEC to a level above 20%, the VREG OUT
LDO regulator and 2.1 RTN line will be reconnected, pro-
viding power and ground to the application. An output
capacitor on the VREG OUT LDO output will supply energy
for some time following shutdown of the D-MPM101 due to
a deep discharge. The duration of the output energy sup-
ply will depend on the connected load.
Energy Harvesting Input
A pre-charge energy minimum of 350 nJ of energy is
required as a minimum threshold input to initiate charging
of the D-MPM101. Energy provided above the initial pre-
charge energy will then be used as recharge energy to the
D-MPM101. Pre-charge energy will be present for a period
of up to 3 seconds. Since the D-MPM101 does not provide
any input boost circuitry, any electrical power supplied at
J2 must be at a voltage level above the integrated MEC
open circuit voltage that can be measured between pins
J1-1 and J1-2. Depending on the state of charge, the MEC
connected to the D-MPM101 will typically have an open
circuit voltage between 3.9V and 4.1V.
Input power must also be limited to less than 150mW. Any
connected energy supply devices must be evaluated for
peak continuous power. Power levels that exceed 150mW
for any extended period of time will cause damage to the
D-MPM101 circuits and may permanently damage or
destroy the device.
Two separate inputs are provided, one for AC input, such
as that provided by an unregulated piezoelectric device,
and one for DC input, such as that provided by photoelec-
tric cells. The input network for the AC and DC networks
are shown in Figure 5 and Figure 6 respectively.
Typically, applied AC energy harvesting devices include
piezoelectric elements or inductively coupled coils
designed to gather energy from inductively coupled charge
sources. Any AC excitation power greater than the input
threshold of 120 nW will allow charging of the MEC to
commence. Small or low-impedance (high internal leak-
age) energy harvesting devices may require an additional
input capacitor or filter network to sustain sufficiently high
input voltages for recharge.
Typically, applied DC energy harvesting devices include
photovoltaic cells or thermoelectric generators. No pre-
conditioning of the source energy is required as long as
the input power does not exceed 150 mW continuously.
Short duration power pulses in excess of 150 mW may be
tolerated, but no guarantee is made regarding the duration
which power levels exceed the maximum input power level
may be withstood by the D-MPM101 electronics before
permanent damage occurs to the components or the MEC.
Low Drop-Out Regulator
The regulated LDO or Low Drop-Out Regulator is provided
to supply a constant regulated voltage source. In order to
enable the regulated output, pin J5.3 VREG EN IN must be
connected to pin J5.4, VREG EN OUT. Additionally, Pin
J5.1, 2.1 EN IN must be tied to pin J5.2, 2.1 EN OUT.
Figure 7 indicates the timing required to fully power the
output LDO regulator at pin J5.7, VREG OUT.

INFINERGY™ D-MPM101: Integrated Solid-State Micro-Power Storage Module
As shown in Figure 4, page 6, the output of the LDO regu-
lator will be tied to the output voltage of the MEC. Due to
the intrinsic drop out voltage of the regulator, the output of
the regulator will always be at least 0.3V under the voltage
of the MEC under load.
Direct Connection to the MEC
A direct connection to the MEC can be achieved by con-
necting a load to pins J1.1 and J1.2, MEC+ and GND
respectively. By connecting any load or other device to
these pins, the internal charge and discharge manage-
ment and protection systems are completely bypassed.
Shorting or over-discharging the MEC integrated into the
D-MPM101 will cause damage or permanent failure of the
MEC. Additionally, any charge energy applied in excess of
the maximum charge voltage of 4.10V will cause an over-
charge condition and may damage the MEC.
Additional MECs can be added at this port allowing the
user to increase the total capacity of the D-MPM101. How-
ever, any cells connected to this port must be connected in
a parallel configuration as shown in Figure 8. Cells may
not be connected in series at this port. D-MPM101 units
may be connected in series as long as the charging net-
works for each D-MPM101 unit are electrically isolated
from all other D-MPM101 units, as shown in Figure 9,
page 9.
