Figure 10. Overcurrent Protection Circuit
At the other end of the V_DC input range, the current will be somewhat less. At 14.0V, for
example, the corresponding power could be produced with only 3.0A. In this example, a
comparator, U1A, will be used to sense when V_DC is over 14.0V and will shift the current limit
from 6.0A to 3.0A.
Let Delimited)= 6.0A
Let I_DC(limit2)= 3.0A
Let b(Q1)= 100
Let R1= 5 m
