3 Description
The bq2970 battery cell protection device provides an
accurate monitor and trigger threshold for overcurrent
protection during high discharge/charge current
operation or battery overcharge conditions.
The bq2970 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.
