* b) Auto start (Pin 9 open)
The circuit behaves as written under α_max (V₉ = 0),
with the exception that Pin 6 is not connected to
GND. If the value of V₆ decreases to 25% of the
threshold value (V_T25), the circuit becomes active
again with soft-start.
c) I_max (V₉ = V₈)
When V₆ has attained the overload threshold
maximum value i.e. V₆ = V_T100; Pin 13 is switched
to Pin 8 (V_Ref) through the resistance R (= 2 kW)
without soft-start capacitor discharging at Pin 7.
With this mode of operation, direct load current
control (I_max) is possible. A recommended circuit is
shown in figure 18.
