Part Number : BQ294502
Function : Overvoltage Protection for 2-Series and 3-Series Cell Li-Ion Batteries
Package : WSON 6 Pin
Maker : Texas Instruments
Pinouts : 
Description :
The BQ294502, 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.
