Description

The TSSOP 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 TSSOP is a key  component in applications requiring remaining  capacity estimation, safety monitoring, and batteryspecific data storage.
