Power management products that convert energy from Vibration (Piezo), PhotoVoltaic (Solar) and Thermal (TEC, TEG, Thermopiles, Thermocouples) sources provide high efficiency conversion to regulated voltages and charge batteries and/or super capacitor storage elements. These Energy Harvesting ICs automatically manage ambient and battery energy to dramatically extend the run time of a primary battery. Boost converters that operate from as little as 20mV or battery chargers with Maximum Power Point capability expand the possibilities for a wide variety of industrial automation and control, wireless sensor, transportation, automotive and building management applications. Ultralow quiescent current linear regulators, op amps, comparators, voltage supervisors, analog-to-digital converters, digital-to-analog converters and micropower voltage references provide additional fundamental building blocks required for autonomous systems.
