Abstract
Digital isolator devices, and many other devices, have a maximum device junction temperature, which, if exceeded, may cause device failure and the integrity of the isolation is no longer guaranteed. The use of an electronic fuse, eFuse, arranged in series with the digital isolator, provides a protection scheme for the digital isolator in which current is limited by the eFuse when it is determined that the supply current of the digital isolator exceeds a predetermined threshold that would the cause junction temperature to increase above an absolute maximum rating. As such, the integrity of the digital isolator is preserved in the event of a system fault.
