LM1946 Over Under Current Limit Diagnostic Circuit February 1993 LM1946 Over Under Current Limit Diagnostic Circuit General Description The LM1946 provides the industrial or automotive system designer with over or under current limit detection superior to that of ordinary transistor or parator-based circuits Each of the five independent parators can be used to monitor a separate load as either an over current or under current limit detector Two parators 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 Provisions for...
