High-Precision Coulomb Counter IC Evaluation Kit

Please check latest availability status for a specific part variant.


The DS2740 evaluation kit (EV kit) makes performance evaluation, software development, and prototyping with the DS2740 high-precision coulomb counting IC easy. The evaluation board interfaces to a PC running Windows XP or older through a DS9123O USB adapter and RJ-11 cable connection.

The DS2740 EV kit evaluation software gives the user complete control of all functions of the DS2740. Separate control tabs allow the user access to all memory locations, all status registers, and real-time updates of all monitored parameters. The software also incorporates a data-logging feature to monitor a battery over time.

The evaluation board circuit is designed to provide the DS2740 with accurate parameter measurements and protect the DS2740 from ESD damage.
