13.4 Reference circuits
Some typical examples of port power switching and overcurrent detection modes are
given in
Figure 11
to
Figure 14
.
The RC circuit (10 k
and 0.1
μ
F) around the PMOS switch provides for soft turn-on.
The series resistor connecting the SP/BP pin to V
CC
tunes up the overcurrent trip
voltage slightly (see
Figure 10
). In the schematic diagram the resistor separates the
net names for pins V
CC
and SP/BP. This allows an automatic router to use a wide
trace for V
CC
and a narrow trace to connect pin SP/BP.
