  • Windows XP-, Windows Vista-, and Windows 7-Compatible Software
  • Proven PCB Layout
  • Fully Assembled and Tested

Product Details

The MAX17048/MAX17049 evaluation kits (EV kits) consist of the MAX17048/MAX17049 evaluation kit (EV kit) and the Maxim DS91230+ command module. A Windows XP®-, Windows Vista®-, and Windows® 7-compatible software is also available for use with the evaluation kits and can be downloaded from www.maximintegrated.com/evkitsoftware.
The EV kits are fully assembled and tested surface-mount PCBs that evaluate the MAX17048/MAX17049 host or battery-side fuel gauge for 1-cell/2-cell lithium-ion (LI+) batteries in handheld and portable equipment. The EV kits can be powered from a single battery (MAX17048) and can be configured to evaluate a single lithium cell (MAX17048) or two lithium cells in series (MAX17049).

Applications

  • Digital Still and Video Cameras
  • e-Readers
