About BQ24165 / BQ24167 " Termination Current " when Charge Half Function by JEITA or CE1/CE2 Pin Control

Hi 

I had this question for last time. 

Thank you very much , I understood this spec. 

  >I have one question for  BQ24165 / BQ24167   Current Half Function,

  >These device Charge current  Min is  550mA. 

  >But these device has Current half mode.

  >1) BQ24167    =>  JEITA   Function   0.5C   at  temp  between T1 and T2 .

  >2) BQ24165   => CE1/ CE2 Pin control Function  at  CE1=0 and CE2=0 

 

But , I have other question  for this one.

【　New  Question 】

 This is last time question  and answer. 

    >If we did Charge current set to 550mA (Min Spec) , and if  these 1) 2)  function or Pin control.

    >Dose  Charge current  to  Half  current  ( 275mA)   by  JEITA Function or CE1/2 Pin Control   ??  

    >Or  keep Charge Current ??  Could you tell us this one ??

And this is Answer 

    >The charge current will be reduced by 1/2 even if max charge current is set to 550mA.

New Question 

  How about Termination current  when reduced by 1/2?? 

 

 1) BQ24167    =>  JEITA   Function   0.5C   at  temp  between T1 and T2  

          =>  What is Termination Current ??   " Termination  Current Disable"   or  10% of  Half  Current  or  Before Half current  ??

 2) BQ24165   => CE1/ CE2 Pin control Function  at  CE1=0 and CE2=0 

         =>  What is Termination Current ??     same as BQ24167 Spec ?? 

Could you tell as this Termination Current spec when  when Charge Half Function

by JEITA or CE1/CE2 Pin Control ?? 

Thanks and Regard

    Termination is disabled during when temp is between T1 and T2.

    Hi Jeff

    Thank you very much.
    I understood BQ24167 Termination Disable between T1 and T2.
    How about Termination Current BQ24165 when Charge Current Half Function CE1/CE2 ??

    Data Sheet Table 2. CE1, CE2 Input Table
    CE1 CE2 FUNCTION
    0 0 Normal Charging
    0 1 Charge current reduced by half <=====
    1 0 VBAT(REG) reduced to 4.06 V
    1 1 Charging Suspended


    Termination Current value dose not change and same as I chg 10% ??

    For instance
    I chg setting 1A , Termination Current is 0.1A,

    If "Charge Current Reduce by Half " CE 1 /CE2 Control
    I chg change to 0.5A , Termination Current is 0.05A ??

    or

    I chg change to 0.5A . Termination Current 0.1A ?? * Keep Original Value ??

    Which is correct ??


    I think BQ24165 Termination Function dose not disable , because of Control by CE1/CE2.

    Termination is disabled for 165 when CE1 = 0 and CE2 = 1.
