产品说明
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. The output is reset (goes low) if the cell voltage drops below the set threshold minus the hysteresis.
