View Detailed Evaluation Kit Information

The DS2751K evaluation kit makes performance evaluation, software development, and prototyping with the DS2751 multichemistry battery fuel gauge easy. The evaluation board interfaces to a PC through a DS9123 serial port adapter and RJ-11 cable connection. The provided CD-ROM contains all related data sheets along with the evaluation software, which can be run under Windows® 95, Windows 98, or Windows NT.

The DS2751K evaluation software gives the user complete control of all functions of the DS2751. Separate control tabs allow the user access to all EEPROM and RAM memory locations, all control registers, and real-time updates of all monitored parameters. The software also incorporates a data logging feature to monitor a cell over time and fuel-gauging algorithms to improve remaining capacity calculations based on specific cell characteristics.

The evaluation board circuit is designed to provide the DS2751 with accurate parameter measurements and protect the DS2751 from ESD damage. Kit demonstration boards will vary as they are improved upon over time. For information on the demonstration board circuits refer to the documentation directory on the DS2751K CD-ROM.
