Overview

The LTC3108EGN-1 is a micropower energy-harvesting power manager designed to extract and manage energy from very low-voltage sources such as thermoelectric generators (TEGs) and thermopiles. It supports inputs down to about 20 mV and up to about 500 mV and integrates the boost/management functions needed to charge an energy store and power low-power electronics. The part is supplied in a 16-lead SSOP package suitable for surface-mount PCBs.

Why Choose This Part

The LTC3108 family is purpose-built for ultra-low-voltage sources, with a guaranteed cold-start and operation from inputs down to the tens of millivolts range. Its integrated boost and power-management features reduce external component count and simplify designs for battery charging or supercapacitor energy storage. The SSOP-16 package and existing reference designs make it straightforward to prototype and deploy in space-constrained, low-power applications.

Applications

Thermoelectric energy harvesting
Harvesting power from small temperature differentials (TEGs) to run remote sensors or telemetry.
Battery-less or intermittently powered wireless sensors
Powering low-duty-cycle IoT sensor nodes and BLE/LoRa transmitters that operate from harvested energy.
Wearable or body-powered sensors
Converting tiny voltages from body heat or small thermopiles to power low-power biomedical or activity sensors.
Industrial temperature-differential monitoring
Supplying condition-monitoring sensors in environments with small but persistent temperature differences.

Getting Started

Start by downloading the LTC3108 datasheet and the manufacturer's application notes and reference schematics to see recommended external components and layout guidance. Look for the official evaluation kit from Analog Devices/Linear Technology to speed prototyping; use the reference BOM and PCB layout for best performance with micro-power sources. Plan for a low-leakage energy storage element (small rechargeable cell or supercapacitor) and test with a representative low-voltage source (thermopile or TEG) rather than a conventional bench supply to validate real-world behavior.
