Description for the BQ294533

The bq2945xx family of products is a secondary-level voltage monitor and protector forLi-Ion battery pack systems. Each cell is monitored independently for an overvoltage condition.Based on the configuration, an output is triggered after a fixed delay if any of the two or threecells has an overvoltage condition. This output is triggered into a high state after an overvoltagecondition satisfies the specified delay timer.
