General Description

The BQ2946xx family of products is a secondary-level overvoltage monitor and protector for Li-Ion battery pack systems.

The cell is monitored for overvoltage condition and triggers an internal counter once the OVP threshold is exceeded;

after a fixed set delay, the out is transitioned to a high level.
