Product Details

The DS2762 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 DS2762 is a key component in applications including remaining capacity estimation, safety monitoring, and battery-specific data storage.

Applications

  • Cell Phones/Smartphones
  • Digital Cameras
