Product Summary

The UC1903 family of quad supply and line monitorintegrated circuits will respond to under- andover-voltage conditions on up to four continuouslymonitored voltage levels. An internal op-amp inverterallows at least one of these levels to be negative. Aseparate line/switcher sense input is available toprovide early warning of line or other power sourcefailures.
