... CBC-EVAL-10 can be configured to operate in any of three modes, as required by the application. The operating mode is set by configuring the various jumpers on the CBC-EVAL-10. [See Figure 3 and the associated tables for jumper settings associated with each of the operating modes.] The three operating modes are as follows: 1 ...

... CBC3150 charge pump. Use of these two control lines is optional. There are several connectors on CBC-EVAL-10 for connection to target devices to be powered. Either the J9 or J10 connector can be used for low power microcontroller-based systems. In the case of a low power wireless end device, the CBC-EVAL-10 has storage energy for approximately 1000 radio transmissions - depending on protocol used - in no/low ambient light conditions ...

... Specifications subject to change without notice. CBC-EVAL-10 Circuit Schematics As a result of designing the CBC-EVAL- versatile and useful for designing to any number of operating environments and system requirements, there are many circuit elements that will not be necessary for any given CCEH implementation. The full schematic of Figure 4 depicts the CBC-EVAL-10 in its entirety. A simpler and more often used embodiment is shown in Figure 5 ...

... Once the peak power point of the PV cell has been determined, the CBC3150 operating point can be adjusted to match the PV cell. This is done by adding a resistor divider R2 and R3 to the CBC-EVAL-10 module. As shipped, those resistors are not populated. Cut the solder trace in the R2 location prior to adding the resistor. ...

... The CHARGE/ line on the CBC-EVAL-10 has a 1.0MΩ pull-up resistor with a very slow rise time. Use an internal microcontroller pull-down resistor to force the CHARGE/ line low all of the time and then disable the pull-down resistor to check the state of the line. This will keep the CHARGE/ line from biasing the input at mid level for long periods of time, which could case large parasitic currents to flow ...

... This depends on many factors, including load power consumption, EnerChip state-of-charge, operating temperature, etc. The EnerChips on the CBC51100 module provide 100µAh of discharge capacity when fully charged. Q: How long will the CBC-EVAL-10 module last if I use it every day and input power is available most of the time? A: The CBC-EVAL-10 module should last at least 10 years. ...
