UCC3913
Although the UCC3913 is designed to provide system
protection for all fault conditions, all integrated circuits
can ultimately fail short. For this reason, if the UCC3913
is intended for use in safety critical applications where
UL or some other safety rating is required, a redundant
safety device such as a fuse should be placed in series
with the device. The UCC3913 will prevent the fuse from
blowing for virtually all fault conditions, increasing system
reliability and reducing maintenance cost, in addition to
providing the hot swap benefits of the device.
