Dear TI Team,
I have been using external balancing on bq76952 as in the image from the application note shown below.
I have noticed that on 10th and 5th cell balancing is turned on periodically when:
- For 10th cell: 11th cell is being balanced. But not then both 11th and 9th cells are being balanced
- For 5th cell: 6th cell is being balanced. But not then both 6th and 4th cells are being balanced
The scope shot across CE of external balancing NPN for 10th cell is as in the image below
Notice that how the turn ON is in synch with the 525 msec balancing turn off time period for voltage measurements and 1 sec time period for COV and CUV measurements.
Please help me with this issue.
Thanks and Regards
