Product Details

The MAX1908 evaluation kit (EV kit) is an accurate and efficient multichemistry battery charger. It uses analog inputs to control charge voltage and current. The EV kit can charge 2 to 4 series lithium-ion (Li+) cells with a current up to 3A. High efficiency is achieved by a buck topology with synchronous rectification. The EV kit provides outputs that can be used to monitor the input current, the battery-charging current, and the presence of an AC adapter.

Applications

  • Handheld Terminals
  • Notebook and Subnotebook Computers
  • PDAs and Other Handheld Devices
