LONDON – Maxim Integrated Products has introduced the MAX17710, which it claims is the industry's first IC to integrate all of the power-management functions for ambient energy harvesting, as well as for charging and protecting micro-energy cells (MECs), a form of solid-state battery.
The MAX17710 accepts energy from a variety of poorly regulated energy harvesting sources with output levels ranging from 1 microwatt to 100-mW. Examples include light captured by photovoltaic cells, vibration captured by a piezoelectric element, heat captured by a thermoelectric generator, and RF obtained from near-field communications.
The MAX17710 integrates a programmable input boost regulator to charge a MEC with energy sources as low as 0.8-V.
The chip is packaged in a low-profile 0.5-mm TQFN. The IC will also be available in wafer form to enable even thinner form factors.
Maxim (Sunnyvale, Calif.) has worked with Infinite Power Solutions Inc. (Littleton, Colorado), the manufacturer of the Thinergy solid-state, rechargeable MEC battery products.
"When combined with ambient energy harvesting, MECs uniquely enable autonomous, perpetually powered solutions for decades of use," said David Squires, vice president of business development for Infinite Power Solutions, in a statement issued by Maxim.
Pricing for the MAX17710 starts at $4.11 in quantities of 2,500. An evaluation (EV) kit featuring the MAX17710 PMIC, Thinergy MEC101, and solar energy harvesting is also available.
