Figures 4–6 show typical applications for the
MAX16052/MAX16053. Figure 4 shows the MAX16052
used with a p-channel MOSFET in an overvoltage pro-
tection circuit. Figure 5 shows the MAX16053 in a low-
voltage sequencing application using an n-channel
MOSFET. Figure 6 shows the MAX16053 used in a mul-
tiple output sequencing application.
In higher power applications, using an n-channel
device reduces the loss across the MOSFET as it offers

Similarly, if a higher voltage is present in the system, the
open-drain version can be used in the same manner.
