Working Principle

The BQ2083DBTRG4 provides a comprehensive set of features and functions for effectively managing and protecting rechargeable Li-Ion/Li-Poly batteries. It monitors the parameters such as current, voltage, temperature, and various other parameters to protect the battery from potential harm.The BQ2083DBTRG4 works by continuously monitoring the battery parameters and controls the charging process accordingly. It measures the cell voltage during a charge or discharge cycle and limits the current or voltage as necessary to protect the battery from potential harm. The Charge Termination Timer (CITT) is also used to determine when the battery has been adequately charged and the BQ2083DBTRG4 will cut off the charging current.When the BQ2083DBTRG4 detects a fault condition such as an over-temperature or an over-voltage, it will immediately shut down the charging current and signal the user’s board. The device also includes a dedicated register to signal the user’s board when the status of the device has changed and when the faults have been detected.In summary, the BQ2083DBTRG4 is an ideal Integrated Battery Management solution for single cell Li-ION/Li-POLY batteries. It includes a wide range of features and functions that helps protect the battery from potential harm and make the battery management process easier, safer and more efficient.
