parasitic inductance and resistance effects, maximize the
width of the high-current PCB traces.
PGOOD vs Power is Good and Fault Signals
Keep in mind that the -12VOUT is not monitored for under
voltage, thus the PGOOD output signal only takes into
account the three positive supplies. PGOOD will assert once
all minimum positive UV criteria is reached and the M12VO
may not be more than a few volts below ground at that time.
It will pull low once any positive voltage < UV Vth. For
applications that don't use -12V, the M12VI pin on the
ISL6111 is simply grounded. The Fault-not output, FLTN
pulls low once the CR duration has expired and signals that
all supplies have been disconnected from the load. See
Figure 3 for operational PGOOD and FLTN waveforms.
Adjusting the Current Regulation Level
The current regulation level is adjusted by the CRSET
resistance to ground value. The ratio of resistance to CR
change is not linear but is unidirectional in relationship, see
Figures 4-6.
