bq297xx Single-Cell Battery Cell Protection ICs

Texas Instruments bq297xx Single-Cell Battery Cell Protection ICs provide an accurate monitor and trigger threshold for overcurrent protection. This protection is done during high discharge/charge current operation or battery overcharge conditions. The Texas Instruments bq2970 device protects Li-Ion/Li-Polymer cells and monitors across the external power FETs for protection due to high charge or discharge currents. In addition, there is overcharge and depleted battery monitoring and protection. These features are implemented with low current consumption in NORMAL mode operation.
