MAX17710
Energy-Harvesting Charger and Protector
General Description
The MAX17710 is a complete system for charging and
protecting micropower-storage cells such as Infinite Power
Solutions’ THINERGY® microenergy cells (MECs). The IC
can manage poorly regulated sources such as energy-
harvesting devices with output levels ranging from 1FW 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 a low-dropout (LDO) linear regulator with
selectable voltages of 3.3V, 2.3V, or 1.8V. The output regu-
lator operates in a selectable low-power or ultra-low-power
mode to minimize drain of the cell. Internal voltage protec-
tion prevents the cell from overdischarging.
The device is available in an ultra-thin, 3mm x 3mm x
0.5mm 12-pin UTDFN package.
