Extremely precise current limiting is now possible.
For example, I
is set to a static voltage level V
and a propagation delay time t
delay compensation the overshoot is only about 2 % (see
Figure 13
Propagation delay compensation is realized by means of a dynamic threshold voltage V
slope is steeper, driver switch-off takes place earlier to compensate for the delay.
