Could you tell us about question?

[Question]
How much is the Iout(pulse) maximum absolute rating?
Please see figure below.

Hi Tateo,

I moved this thread to the appropriate forum. All eFuse product questions may be posted under "Load Switches".

Thanks!

Hi Tateo,

The peak current through TPS25944 during the output hot- short is limited by the path parasitics (Resistance and inductance) of input supply, chip, short circuit parasitics. The current peaks only till 200nsec of fast trip time and under all practical test conditions, there will not be any reliability issue with such a fast response time.

Regards,

Dilip

Your answer "the output hot- short is limited by the path parasitics (Resistance and inductance) of input supply, chip, short circuit parasitics" probably explained why the fast trip response I got from my scope was as twice as in fig. 70 (48.8A vs 24A).

Exactly Nick. The peak current varies based on the power path parasitics.
