Soldering Temperature See IPC/JEDEC J-STD-020A SpecificationDescriptionThe 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.
