Function : Overvoltage Protection for 2-Series and 3-Series Cell Li-Ion Batteries
Maker : Texas Instruments

Pinouts :
BQ294502 datasheet

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 one of the two or three cells has an overvoltage condition. This output will be triggered into a high state after an overvoltage condition has satisfied the specified delay timer.
