SLUSAJ3H – SEPTEMBER 2011 – REVISED DECEMBER 2017 bq2945xx Overvoltage Protection For 2-Series and 3-Series Cell Li-Ion Batteries
1 Features 3 Description The bq2945xx 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. 1 2-Series and 3-Series Cell Overvoltage Monitor
