Figure 48 shows a test example of initial short circuit inrush current limit. Test condition: V
S
= 13.5 V, input is
from low to high, load is short to GND or with 470-µF capacitive load, external current limit is 2 A. CH1 is the
output current. CH3 is the input step.
Figure 49 shows a test example of a hard short-circuit inrush current limit. Test condition: V
S
= 13.5 V, input is
high, load is 5 µH + 100 mΩ, external current limit is 1 A. A short to GND suddenly happens.
