EnerChip™ EH Energy Harvesting Module
Overview
The EnerChip EH CBC5300 is a self-contained
Energy Harvesting power module in a 24-pin DIP
configuration. The CBC5300 module is designed to
accept a wide range of energy transducer inputs,
store the harvested power, and deliver managed
power to the target system. The purpose of this
module is to enable system designers to quickly
develop Energy Harvesting applications. A block
diagram of the EnerChip EH CBC5300 energy
harvesting module is shown in Figure 1.

System Description
The energy harvesting transducer (e.g. photovoltaic
cell, piezoelectric material, thermoelectric converter,
etc.) converts ambient energy into electrical
energy. The output voltage of the energy harvesting
transducer is often too low to charge the EnerChip
batteries and power the rest of the system directly,
so a boost converter is used to boost the energy
harvesting transducer voltage to the voltage needed
to charge the EnerChip and/or power the system.

Applications
• Wireless Sensors - Create perpetual sensors
with ambient energy and no batteries to change.
• Patient Monitoring - Use piezoelectric,
thermoelectric, or photovoltaic transducers to
power patient status sensors.
• Process Control - Sensors and reporting
electronics can be powered with motion or fluid
flow transducers.
• Real Time Location Monitoring - Active RFID
and RTLS sensing devices can be powered using
energy harvesting.
• Environmental Monitoring and Controls -
Optimize energy using energy harvesting.
The charge control block continuously monitors
the output of the boost converter. If the output of
the boost converter falls below the voltage needed
to charge the EnerChips, the charge controller will
disconnect the boost converter from the EnerChips.
This prevents the EnerChips from back-powering the
boost converter in low input power conditions.
The power management block is used to protect
the EnerChips from discharging too deeply in low
input power conditions or abnormally high current
load conditions. The power management block
also ensures that the load is powered up with a
smooth power-on transition. The power management
block has a control line (CHARGE) for indication to
the system controller that the energy harvester is
charging the EnerChips. A control line input (BATOFF)
is available for the controller to disconnect itself
from the EnerChips when it is necessary to conserve
battery life in prolonged low input power conditions.
The EnerChip EH CBC5300 as shown in Figure 2 has
two CBC050 50µAh EnerChip rechargeable battery
cells, for a total 100µAh of capacity.
