3 Description

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.
