Part Number: BQ27Z561-R2
Other Parts Discussed in Thread: BQSTUDIO

Tool/software:

How can I enter the fuel gauge into Hibernate Mode using the BQstudio?

Please provide simple sequence of steps.

How can I be sure it is in Hibernate Mode, as far as I understand i2c communication disables Hibernate Mode.

Thanks Uri

Hello,

Please refer to the following section from the device Technical Reference Manual.

You will know whether the gauge is in hibernate mode depending on if the Operation Status A [HIB] bit is set or not.

Regards,

Jonny.

Hi thanks for your answer.

I sent the toggle hibernate command.

not sure that the fuel gauge entered to this mode.

Can you add the registers flags before toggle and after?

Please add the Operation Status A [HIB] bit as you mentioned in your previous answer.

Thanks,

Uri
