Other Parts Discussed in Thread: BQ76940

I would like to reduce bq76940 cell count to 13, according t3 SLUUB41 FAQ :

"The top cell and bottom two cells of each cell group should be used. For a recommendation on which cells to short, see the table in the data sheet. "

can anyone has schematic that i can follow ?

cheers.

Please refer to the page 43 of bq76940 DS. Table 8-3. Cell Connections for bq76940 describes how to short cells. When cell count is 13, you should short VC14–VC13 and VC9–VC8. Hope it helps.

sorry for overlooked the table 8-3, excellent we can even short more terminals on 76940 to provide 10 cells support that we can have 10s and 13s for 36v and 48v market, also finger-crossed BQ76PL455 coming soon for 60v market.

thanks,

Tiger
