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 regulator operates in a selectable low-power or ultra-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.
The MAX17710 is an integrated power‑management IC designed for charging and protecting micropower storage cells from poorly regulated energy‑harvesting sources. It supports input power from 1 µW up to 100 mW and includes a boost regulator that can start charging from sources as low as 0.75 V.
The device offers selectable low‑dropout regulator outputs of 1.8 V, 2.3 V, or 3.3 V, ultra‑low quiescent currents, and protection features such as over‑voltage shunt and undervoltage lockout. It is supplied in a 12‑pin ultra‑thin UTDFN package (3 mm × 3 mm × 0.5 mm) and is intended for applications like smart cards, RFID tags, medical devices, and remote wireless sensors.
