Figure 9. 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 I_DC(limit)= 6.0A
Let I_DC(limit2)= 3.0A
Let b(Q1)= 100
Let R1=5.0 m
= 0.005
Let R12= 100.0
Let R13= 100.0
Let V(R14)
≈ 1.8V
Let I(R20)
≈ 100.0 A
Let C36= 2.0K
