Thermobility WPG-1


As the first in a series of wireless power generators, the Thermobility WPG-1 provides a constant voltage output of 3.3, 4.1 or 5.0 Vdc to electrical loads of 15k? or higher. The WPG-1 is about the size of a golf ball and consists of a pin-fin heat sink, a custom circuit board, Laird's eTEG™ HV56 thermoelectric power generator module and a metal attachment plate that is applied to the desired heat source. The device incorporates a Linear Technologies LTC®3108 Ultralow Voltage Step-Up Converter and Power Manager chip to provide up to 1 milliwatt of electrical power, and operates at temperature differentials as low as 15-20K relative to ambient. Larger temperature differences can generate significantly more power.

The WPG-1 is designed for ease of use with any flat surface heat source. For simple bench-top testing, the WPG-1 can be placed directly on a laboratory grade hotplate with temperature control. For evaluation with other surfaces, the attachment plate can be mated with either thermal grease for normal horizontal application or double-stick thermal pad for vertical mounting.

The integrated circuit board includes DIP switches for setting the output voltage. Electrical connections can be made using the on-board 2-pin or 6-pin connectors. The 6-pin connector is a Texas Instruments connector that mates to the eZ430 wireless target board, making the WPG-1 an ideal wireless power source for the eZ430 development platform.

Maxim Integrated

The MAX17710 is a complete system for charging and protecting micropower-storage cells such as Infinite Power Solution's THINERGY® microenergy cells (MECs). The IC can manage poorly regulated sources such as energy-harvesting devices with output levels ranging from 1µW to 100mW. The device also includes a boost regulator circuit for charging the cell from a source as low as 0.75V (typ). An internal regulator protects the cell from overcharging.

Output voltages supplied to the target applications are regulated using an efficient adjustable low-dropout (LDO) linear regulator with selectable voltages of 3.3V, 2.3V, or 1.8V. The output regulator operates in a selectable high-power or low-power mode to minimize drain of the cell. Internal voltage protection prevents the cell from overdischarging. The device is available in an ultra-thin, 3mm x 3mm x 0.5mm 12-pin UTDFN package.


  • Integrated Power-Management IC for Energy Storage and Load Management
  • Lithium Charger
    • 1nA Standby IQBATT
    • 625nA Linear Charging
    • 1µW Boost Charging
  • Lithium Cell Undervoltage Protection
  • Charger Overvoltage Shunt Protection
  • 1.8V, 2.3V, or 3.3V LDO (150nA IQBATT)
  • Lithium Cell Output Buffering
  • Ultra-Thin, 3mm x 3mm x 0.5mm UTDFN Package
