DESCRIPTION
The DS2760 High Precision Li-Ion 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 data storage, and Li-Ion protection into the small footprint of either a TSSOP package or flip-chip. The DS2760 is a key component in applications including remaining capacity estimation, safety monitoring, and battery-specific data storage.
