DC2042A: Multi-Source Energy Harvesting

Summary

The DC2042A is a versatile energy harvesting demo board that is capable of accepting piezoelectric, solar, 4mA to 20mA loops, thermal-powered energy sources or any high impedance AC or DC source. The board contains four independent circuits consisting of the following EH ICs: LTC®3588-1: Piezoelectric Energy Harvesting Power Supply; LTC3108: Ultralow Voltage Step-Up Converter and

Power Manager; LTC3105: Step-Up DC/DC Converter with Power Point Control and LDO Regulator; LTC3459: 10V Micropower Synchronous Boost Converter; and LTC2935-2/LTC2935-4: Ultralow Power Supervisor with Power-Fail Output Selectable Thresholds.

The board supports the following interconnects: Direct connection with the Dust Mote demo boards; the DC9003A-B Mote on a chip or the DC9003A-A Manager on a chip; and Energy Micro STK development kit.

In addition, many turrets are provided and one transducer header is available to make it easy to connect transducers to the board.

The board contains multiple jumpers that allow the board to be configured in various ways. The standard build for the board has three jumpers installed out of the possible 10 jumpers. The board is very customizable to the end users’ needs. This compatibility makes it a perfect evaluation tool for any low power energy harvesting system.

Please refer to the individual data sheets for the operation of each power management circuit. The application section of this demo manual describes the system level functionality of this board and the various ways it can be used in early design prototyping.
