The bq297xy device provides the protection functions for 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.
Features
- Over and under voltage, over current, and short circuit fault detection
- Zero-Volt charging for depleted battery
- Low operating current
- This circuit is tested and includes functional EVM and User's Guide.
