Ultra-Low Voltage

Energy Harvester and

Primary Battery Life Extender

DescripTion

FeaTures

The LTC^®3107 is a highly integrated DC/DC converter de-

signed to extend the life of a primary battery in low power

wireless systems by harvesting and managing surplus en-

ergyfromextremelylowinputvoltagesourcessuchasTEGs

(Thermoelectric Generators) and thermopiles. The step-up

topology operates from input voltages as low as 20mV.

Battery In-Use Indicator (BAT_OFF)

Using a small step-up transformer, the LTC3107

provides a complete power management solution for

typical wireless sensor applications that operate from a

primary battery. The 2.2V LDO can be used to power an

external microprocessor, while the main output voltage

automatically adapts to match the voltage of the primary

battery. The LTC3107 seamlessly transitions from battery

power to harvested power whenever harvested energy is

available, extending the life of the battery. The BAT_OFF

indicator can be used to track battery usage. An optional

storage capacitor accumulates excess harvested energy,

further extending battery life.
