TPS25221: Current-Limit Threshold Equation

Takashi Yamaguchi

Part Number: TPS25221

Hi team,

I have a question about the Current-Limit Threshold Equation in the d/s.

The d/s describes the  Current-Limit Threshold Equation as follows.

IOS(max)=52640V / Rlim^0.97

IOS(typ)=55960V / Rlim^1.004

IOS(min)=56850V / Rlim^1.033

I think the numerators of IOS(max) and IOS(min) are reversed.　Therefore, I think the following equation is correct. Is my understanding correct?

IOS(max)=56850V / Rlim^0.97

IOS(typ)=55960V / Rlim^1.004

IOS(min)=52640V　/ Rlim^1.033

Also, could you please revise IOS(max) and IOS(min) in the Fig.24? These are reversed.

Regards,

Yamaguchi

    Hi Yamaguchi,

    The formula is correct without needing modification.

    Please double confirm.

    Figure24  indeed has something wrong with wrong label.

    Will correct later.

    Thanks for reminding.

    For TI's policy, I will first click resolved button.
