Genius 4990 points
Part Number: BQ40Z50-R1


Hello Sir:

Please help us to check our schematic.

If there is any thing wrong please let us know.

The other if we connected BTP_INT to B-GND, is it acceptable?

Please let us know your recommendations.

Thanks a lot.

    Hello Statham,

    There are only a few points I would make, I'm not sure why the FUSE outputs of diodes protection, the gauge uses the FUSE pin as an input as well in case the secondary protector trips it will also cause the gauge to trip the FUSE.

    The BTP_INT can be left floating, it is an output. The general rule is to ground inputs and float outputs.

    I would also double check the LED configuration, I didn't have time to confirm this matches the EVM recommendation for the charlieplexing.

    Sincerely,

    Wyatt Keller
