In a 10-lead, 3 mm x 3 mm DFN package, the LTC3107 integrates energy harvesting and power management capabilities to extend the useable life of a primary battery. The device harvests energy from thermoelectric generators and thermopiles when these sources are available, storing excess power in a storage capacitor and transitioning to the primary cell to power a wireless sensor node when harvested power is unavailable. Features include inputs as low as 20 mV, a 2.2V LDO output, and an industrial version, the LTC3107IDD, is available with an operating temperature range from -40°C to +125°C. Price for the LTC3107EDD starts at $2.95 each/1,000 and the LTC3107IDD starts at $3.45 each/1,000. A datasheet is located at http://cds.linear.com/docs/en/datasheet/3107f.pdf.
