Evaluation Kits With 2-Cell Voltage Measurement

The DS2778EVKIT+-EVAL evaluation kits (EV kits) make performance evaluation, software development, and prototyping with the DS2778EVKIT+-EVAL 2-cell stand-alone fuel-gauge ICs with Li-Ion (Li+) protector and SHA-1 authentication easy. The evaluation boards interface to a PC through a DS9123O USB adapter and RJ11 cable connection. The provided CD-ROM contains all related data sheets along with the evaluation software, which can be run under any Windows XP or older operating system (OS) that supports USB operation. The DS2778EVKIT+-EVAL EV kit software gives the user complete control of all the DS2778EVKIT+-EVAL 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 DS2778EVKIT+-EVAL with accurate parameter measurements. Kit demonstration boards vary as they are improved upon over time.
