LM1946 LM1946 Over/Under Current Limit Diagnostic Circuit

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 .
