Figure 4. Overcurrent and short-circuit protections management

The total disable time after an overcurrent event can be set sizing properly the external

network connected to the EN\FAULT pin (refer to Figure 4).

Equation 1

tDIS = tdischarge + tcharge

But tcharge is normally very higher than tdischarge, we can consider only the second one

contribution:

Equation 2

Where VDD is the pull-up voltage of the REN resistor.
