The bq2946xx family of products is a secondary-level overvoltage monitor and protectorfor Li-Ion battery pack systems. The cell is monitored for overvoltage condition and triggers aninternal counter once the OVP threshold is exceeded; after a fixed set delay, the out istransitioned to a high level. The output is reset (goes low) if the cell voltage drops below theset threshold minus the hysteresis.
