MAX17710
The MAX17710 is an energy-harvesting battery charger/protector. It is designed to
capture power from unconventional sources such as light, vibrating piezoelectric
elements, thermoelectric modules, radio frequency energy, and magnetic energy.
It takes the electrical signals from these unregulated, sometimes low-voltage
sources and boosts them as needed to enable charging a battery, supercapacitor, or
microenergy cell. While managing the power and protecting the storage device, it
provides a regulated output voltage.
Benefits
