TPS2543 - Can TPS2543 support iPad(2.4A)?

Other Parts Discussed in Thread: TPS2543

Hi,

 

TPS2543 supports iPad(2A), can TPS2543 support iPad(2.4A)?

(Will "Divider 2" allow charging iPad devices at 2.4A?)

"iPad(2.4A) = 5.2V/2.4A" is a new standard of Apple Inc.

 

Regards,

Kanemaru

    As you talked, iPad(2.4A) is new divider mode for iPad, DP/DM =2.7V/2.7V, different from 2.1A/10.5W, DP/DM=2.7V/2.0V.

    TPS2543/6 support 2.1A, doesn’t support 2.4A.

    Hi,Milo

    Thank you for the information.

    I have four questions I want to ask.

     

    [Q1]

    Does TPS2543 confine "charging current" to 1.0A if I change TPS2543 from divider 2 to divider 1(CTL1=1 , CTL=2=0 , CLT3=1)?

     

    [Q2]

    When "ipad of full charge" is connected, does TPS2543 maintain divider 1 ?

    Because there is little "charging current", I think that I don't turn into divider 2.

     

    [Q3]

    If "charging current" is less than 750mA when I charge ipad, does TPS2543 turn into divider 1 from divider 2?

     

    [Q4]

    Are there the results that TPS2543 charged a product of Apple?

    (iphone4 , iphone5 etc..)

     

    Regards,

    Kanemaru

    [Q1]

     [Milo] TPS2543 (CTL1/2/3=101), it is configured as Divider 1 mode (D+/D- is fixed at 2.0V/2.7V), plug in iPhone or iPad, maximum charging current is 1A. 

    [Q2]

    When "ipad of full charge" is connected, does TPS2543 maintain divider 1 ?

    Because there is little "charging current", I think that I don't turn into divider 2.

    [Milo] Yes

     

    [Q3]

    If "charging current" is less than 750mA when I charge ipad, does TPS2543 turn into divider 1 from divider 2?

     [Milo] There is some hysteresis, the charging current of divider 2 back to divier 1 is around 650mA.

    [Q4]

    Are there the results that TPS2543 charged a product of Apple?

    (iphone4 , iphone5 etc..)

    [Milo] You mean charging wave?

    [kanemaru]  I want the list of apple products which you have measured.
