The LM1946 provides the industrial or automotive system designer with over or under current limit detection superior to that of ordinary transistor or comparator-based circuits Each of the five independent comparators can be used to monitor a separate load as either an over current or under current limit detector Two comparators monitoring a single load can function as a current window monitor Current is sensed by monitoring the voltage drop across the wiring harness pc board trace or external sense resistor that feeds the load
