BQ294502, Overvoltage Protection

The BQ2945xy family of products is a secondary-level voltage monitor and protector for Li-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 three cells has an overv
