Dear All

 

I have a question on bq27541.

 

At “DATA COMMANDS” section of the data sheet, “FULLSLEEP” is described as “the state can be detected by monitoring the power used by the bq27541 because any communication will automatically clear it.”

 

But by looking at the access log attached, both 1st time and 2nd time will show “1” at “FULLSLEEP” bit.

 

Please advice me how to clear the FULLSLEEP bit.

 

Best Regards,

Rhino

    Rhino,

    I looked at your logs, and it appears that your gauge never actually goes to sleep. 

    The FULLSLEEP bit is only used when the gauge transitions from active mode to sleep mode.  Since you appear to  be discharging a significant amount of current (>500mA), your gauge will not go to sleep in this mode.  You must decrease your current below the "sleep current" as defined in the data flash in order for the gauge to go to sleep.

    When this happens, the gauge will go into FULLSLEEP mode instead of just SLEEP, and upon being reawoken, the FULLSLEEP bit will be cleared.

    Let me know if this helps,
    Charles
