ISL6116 (-12V)
Figures 6 and 7 show the ISL6116 reconfigured for -12V low
side switch application. The following components were
removed: RG1, R6 & R11. C2 was added (0.047μf 0805
size). In Figure 8, notice that GATE is 0V to fully enhance the
FET because of -12V operation. Also note that PGOOD is
disabled due to low side configuration. Upon power up,
current regulation mode is entered and CTIM is immediately

begins charging. The nominal time-out period is CTIM x
93k ? , and again PGOOD is disabled (see Figure 9). 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
93k ? (see Figure 10).
