For related parts and recommended products to use with this part, refer to: www.maxim-ic.com/MAX17710.related General Description 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 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.
