Other Parts Discussed in Thread: BQ24230

Hi Team,

My customer considers to use bq24230 and has a question.
Is it possible to change the state of EN1 pin and EN2 pin dynamically?
(For example: to change EN2=low to high when charger is enabled)

I would also like to know if it is possible to change the state of #CE pin dynamically.

Best Regards,
Yaita

Hi Wenjia-san,

I would like to confirm one more.

I believe it is possible to disable charging to switch #CE pin Low to High during charging phases(ex: CC fast charge phase).
Is my understanding correct?
Is there any restriction about the timing of switching #CE pin Low to High ?

Best Regards,
Yaita

As soon as /CE pin voltage is above the logic high threshold, the charging will be disabled.

Thanks,
Wenjia
