MAX17710

Maxim Integrated

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 1µW 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 an efficient adjustable low-dropout (LDO) linear regulator with selectable voltages of 3.3V, 2.3V, or 1.8V. The output regulator operates in a selectable high-power or 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.

Features:

  • Integrated Power-Management IC for Energy Storage and Load Management
  • Lithium Charger
    • 1nA Standby IQBATT
    • 625nA Linear Charging
    • 1µW Boost Charging
  • Lithium Cell Undervoltage Protection
  • Charger Overvoltage Shunt Protection
  • 1.8V, 2.3V, or 3.3V LDO (150nA IQBATT)
  • Lithium Cell Output Buffering
  • Ultra-Thin, 3mm x 3mm x 0.5mm UTDFN Package
