ISL6116 (-48V) Figures
ISL6115 (+12V)
Figures 17 and 18 show the ISL6115 in a +12V high side
switch application.
Refer to Figures 19 and 20. After PWRON is asserted,
notice the soft-start ramp of GATE to assure inrush current is
limited. Observe the PGOOD delay as well.

Both Figures 21 and 22 show an OC event; Figure 21 shows
turning on into a short, and Figure 22 shows a short
occurring during normal operation. An OC event occurs
when the current through the sense resistor exceeds the
user programmed OC threshold (see data sheet). The
controller enters CR mode and capacitor CTIM begins
charging. The nominal time-out period is CTIM x 93kΩ.
