Generic Energy Harvesting Adapter Module for Thermoelectric Generators (TEG) Reference Design


Design files


This reference design aims at providing a generic solution for energy harvesting while giving a practical application application for thermoelectric generators (TEG). It is a fully programmable state-machine which runs at 60nA and can enable and disable key functions as they are needed by the system to optimize power consumption. TIDA-00246 acts as a BoosterPack for the MSP430FR5969 LaunchPad development kit (MSP-EXP430FR5969) for use as an ultra-low power state machine.
