Part Number: BQ28Z610
Other Parts Discussed in Thread: BQSTUDIO

Hi

 I found that AOLD current can not adjust by AOLD Threshold,when BIT7 of  ENABLE PROTECTION B  set 0.

So I change BIT7 of  ENABLE PROTECTION B  set 1,AOLD current can adjust by AOLD Threshold.

But  the default  setting of biit 7 in ENABLE PROTECTION B is 0 in TRM.

I want to know can i change   biit 7  in ENABLE PROTECTION B to 1?

    Hi ke,

    Bit 7 in Enabled Protections A and bits 3 and 1 in Enable Protection B are reserved. I cannot recommend the modification of reserved bits from default settings.

    If you believe that these bits are marked as reserved erroneously in bqStudio, please let me know and I will investigate further.

    Sincerely,

    Hi Bryan,

    Thanks for your reply!
    Bit 7 in Enabled Protections A default is 0,so when test AOLD by adjust AOLD Threshold setting ,the AOLD protection current is always 8.5A.
    but set Bit 7 in Enabled Protections A to 1, the AOLD protection current can change by AOLD Threshold setting.
    so please help to confirm if Bit 7 in Enabled Protections A should set to 1,when i need change AOLD protection current .
