INTRODUCTION
The DS2786 evaluation kit (EV kit) makes performance evaluation, software development, and prototyping with the
DS2786 stand-alone OCV-based fuel gauge easy. The evaluation board interfaces to a PC through a DS9123O
USB adapter and RJ-11 cable connection.
Separate control tabs allow the user access to all 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.
The evaluation board circuit is designed to provide the DS2786 with accurate parameter measurements as well. Kit
demonstration boards will vary as they are improved upon over time. For information on the demonstration board
circuits, visit our website at www.maxim-ic.com.
