The MAX17710GB+ is an energy harvesting charger and protector in 12 pin μTDFN package. It is a complete system for charging and protecting micropower storage cells such as Infinite Power Solutions THINERGY microenergy cells (MEC). This IC can manage poorly regulated sources such as energy harvesting devices with output levels ranging from 1μW to 100mW. The device includes boost regulator circuit for charging cell from source as low as 0.75V (typ). An internal regulator protects cell from overcharging. Output voltages supplied to target applications are regulated using 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 cell from overdischarging. The MAX17710 is used in high temperature applications, semi active RFID tags, memory and real time clock back-up, remote wireless sensors and powered/smart cards.
