The DS2764 high-precision Li+ battery monitor is a data-acquisition, information-storage, and safety-protection device tailored for cost-sensitive battery pack applications. This low-power device integrates precise temperature, voltage, and current measurement, nonvolatile (NV) data storage, and Li+ protection into the small footprint of either a TSSOP package or flip-chip package. The DS2764 is a key component in applications requiring remaining capacity estimation, safety monitoring, and battery-specific data storage.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The DS2764 evaluation kit (EV kit) makes performance evaluation, software development, and prototyping with the DS2764 Lithium-Ion Battery Monitor easy. The evaluation board interfaces to a PC through a DS9123O USB Port Adapter and RJ-11 cable connection.
The DS2764 EV kit evaluation software gives the user complete control of all functions of the DS2764. Separate control tabs allow the user access to all EEPROM and RAM 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 and fuel gauging algorithms to improve remaining capacity calculations based on specific cell characteristics.
The evaluation board circuit is designed to provide the DS2764 with accurate parameter measurements, allow the DS2764 to disable charging or discharging, and protect the DS2764 from ESD damage. Kit demonstration boards will vary as they are improved upon over time. For information on the demonstration board circuits refer to the individual board datasheets located online at www.maximintegrated.com.
