Tool/software:

Dear Sirs and Madams,

We are considering using the BQ25720.

What happens if the CE terminal goes low while the BQ25720 is operating?

What happens to the parameters that learned the battery characteristics during operation?

Will the parameters that were updated before CE went low remain, and will learning continue when CE returns to Hi?

Regards,

Masashi

Hello Alan,

I understoodd that when CE is 'L', the device is disabled and therefore the data during the learning cycle is not retained.

Therefore, I think the Ra Tables in flash will not be updated, but please comment if I'm wrong.

Regards,

Masashi
