... DIP Module Connecting the CBC5300 to the System The CBC5300 board has two control lines that can be connected to a microcontroller (MCU) for the purpose of conserving available energy, using incoming power efficiently, and extending EnerChip battery life. The table below describes the functionality of the connector pins. ...

... Preliminary As configured, the CBC5300 will operate with many transducer types. However, performance specifications of transducers - namely output impedance - will affect the power conversion efficiency of the CBC5300 kit as designed. Please contact Cymbet Applications Engineering at the phone number shown below to discuss your specific application and desired transducer(s). ...

... Preliminary System Level Considerations when Using a Low Power Energy Harvester The CBC5300 is capable of supplying 10s to 100s of µW of continuous power to the load. Most applications operating with radios and microcontrollers typically need 10s to 100s power under peak load conditions. The disparity between what is available and what is needed can be made up by limiting the amount of time the load is powered and waiting sufficient time for the energy harvester to replenish the energy storage device before the subsequent operation commences ...

... 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 ...

... This depends on many factors, including power consumption, EnerChip state-of-charge, operating temperature, etc. The on-board EnerChips provide 100µAh of discharge capacity when fully charged. Q: How long will the CBC5300 module last if I use it every day and input power is available most of the time? A: The CBC5300 module should last at least 10 years ...
