BQ27545-G1: BQ27545-G1: hibernate mode

Part Number: BQ27545-G1

Hi

The customer want to know the method to verify the chip is in the hibernate mode.

A non-destructive inspection method is required. Measuring power consumption is not non-destructive.

REGIN is connected to P+, and theoretically the voltage of this pin will not change. The VCC pin has been tested. Whether it enters hibernate or not, its voltage to P- is 2.5V and does not change.

Is there a nondestructive method to check the hibernation mode?

Waiting for your reply.

Thanks

Star

    Hi Star,

    Can you go more in depth about the testing setup for this?

    If you are able to communicate to the gauge, hibernate mode can be confirmed by if the Control Status [HIBERNATE] = 1 along with these other conditions being cleared.

    Regards,

    Hi Anthony

    Thanks for your reply.

    The customer want to know how to make sure the gauge is in the hibernate. 

    [HIBERNATE] = 1 means preparing to enter sleep mode but not already entering sleep mode. Are there other conditions besides [HIBERNATE] = 1? For example, voltage changes and output current changes must be guaranteed to be within a certain range.

    I suggest the customer to measure the power consumption, but they need for non-destructive testing solutions.

    Please give some suggestions.

    Thanks

    Hi Star,

    Checking to see if the average cell current is below the set Hibernate Current could be able to tell if the gauge has entered Hibernate:
