Product Details

The DS2784 evaluation kit (EV kit) allows easy performance evaluation, software development, and prototyping with the DS2784 1-cell stand-alone fuel gauge IC with Li-Ion (Li+) protector and SHA-1 authentication. The evaluation board interfaces to a PC through a DS9123O USB 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 XP® or older operating system that supports USB operation.

The DS2784 EV kit evaluation software gives the user complete control of all the DS2784 functions. Separate control tabs allow the user access to all EEPROM and RAM memory locations, control registers, real-time updates of all monitored parameters, and SHA-1 functions. The software also incorporates a data-logging feature to monitor a cell over time.

The evaluation board circuit is designed to provide the DS2784 with accurate parameter measurements. Kit demonstration boards vary as they are improved upon over time.
