GENERAL DESCRIPTION

FEATURES

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

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.
