safety recommendations

Although the UCC3912 family is designed to provide system protection for all fault conditions, all integrated

circuits can ultimately fail short. For this reason, if the UCC3912 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 UCC3912 will prevent the fuse from blowing virtually for all fault conditions,

increasing system reliability and reducing maintenance cost, in addition to providing the hot swap benefits of

the device.
