Description

General part information

BQ294504 Series

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 overvoltage condition. This output is triggered into a high state after an overvoltage condition satisfies the specified delay timer.
