ISL6118 (+5V x2)
Figures 61 and 62 show the ISL6118 dual power supply
controller. This IC provides fully independent OC fault
protection for the +2.5V to +5.5V environment, with
integrated MOSFETs. For ease of testing, EN1 and EN2
were tied together on this board.
Refer to Figures 63 and 64. After EN is asserted, notice the
soft-start ramp of both outputs to VIN, in this case +5V. Also

notice that FAULT2 is only an indicator of an OC timeout,
thus is not an indicator of under voltage conditions.
Figure 65 shows an OC condition occurring through
channel 2 of the IC. Note that channel 1 stays up regardless
of the condition of channel 2. Figure 66 shows turning on
into an OC condition on channel 2. Again, channel 1 is
unaffected.
