safety considerations
Although the UCC3918 is designed to provide system protection for all fault conditions, all integrated circuits
can ultimately fail short. For this reason, if the UCC3918 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 power device. The UCC3918 prevents 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.
