Product Details

The DS2775–DS2778 evaluation kits (EV kits) make performance evaluation, software development, and prototyping with the DS2775–DS2778 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 DS2775–DS2778 EV kit software gives the user complete control of all the DS2775–DS2778 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 DS2775–DS2778 with accurate parameter measurements. Kit demonstration boards vary as they are improved upon over time.
