The SS pin has an internal 6V zener clamp (see the
Functional Diagram).
Fault Conditions: Overcurrent Latchoff
The SS pin also provides the ability to latch off the
controllers when an overcurrent condition is detected. The
SS capacitor is used initially to limit the inrush current of
all three output stages. After the controllers have been
