Preliminary
The CBC5300 energy harvester module has a feature for disabling the on-board EnerChip thin film batteries. A
handshake line BATOFF is provided for use of this feature. A high level will disable the EnerChips. This is useful
in very low ambient energy conditions to steer all of the available energy into the load. EnerChip batteries have
very low self-discharge rates (typically 2.5% per year) so it is not necessary to continuously charge them.
Troubleshooting Test Procedure
DS-72-06 Rev06
1) Using a voltmeter, put the ground lead on pin 24 and probe V
This test verifies operation of the input power transducer.
2) Probe right side of the tantalum capacitor (brown bar side) on the CBC5300 module. Voltage should be
between 4.5V and 9V depending on ambient light and battery state-of-charge. This test verifies operation of
the boost converter.
3) Probe V
capacitor voltage reaches 3.8V, V
from zero volts to the voltage across V
charging if the EnerChips are depleted. When the CBC5300 is first powered up, the CBC5300 will first charge
the EnerChips, then charge the output capacitor connected to V
capacitor is charged.
4) Probe V
5) Probe V
6) Probe CHARGE (pin 4). This pin should be at zero volts if the EnerChips are charged and enough ambient
energy is available to operate the CBC5300 module. Depending on the input impedance of the voltmeter, a
high level on this pin would read between 1.0V and 3.5V.
If none of the above works, check pin 1 on one of the EnerChips on the CBC5300 module (with it plugged
into the target application board), as indicated in the figure below. It should read approximately 3.9V. If the
voltage is less than 3.0V, the EnerChips have been damaged.
In applications where a radio is being used - as in wireless sensor netorks - there can sometimes be external
electrical interference with the radio signal that causes the radio receiver to stay on longer than normal. If
this happens, the CBC5300 output capacitor will become discharged and the low battery cutoff circuit will
engage, isolating the EnerChips from the load. If this happens it can take from several minutes to an hour or
more for the EnerChips and output capacitor to be recharged.
