SSPC. Therefore the case, POWER IN, and Control Circuit are
all electrically isolated. FIGURE 1 shows this isolation as the
"ISOLATED CONTROL CIRCUIT."
The electrical isolation is supported by an internal power oscilla-
tor that electrically isolates separate internal power supplies that
will power the internal analog and digital monolithics. This isola-
tion prevents load or logic ground loops from affecting the prop-
er operation of the SSPC. The isolation also insures that a fault
of the switch (MOSFET) could never propagate back into the
SSPC logic or cause damage to the logic side.

Status 1 indicates a logic LOW if > 15% of the rated current is flowing.
Status 2 indicates a logic LOW if the SSPC is tripped due to overcurrent.
