LM1851, LM1 Datasheet (National Semiconductor)

LM1851, LM1, Ground Fault Interrupter

The LM1851 is designed to provide ground fault protection for AC power outlets in consumer and industrial environments Ground fault currents greater than a presettable threshold value will trigger an external SCR-driven circuit breaker to interrupt the AC line and remove the fault condition In addit

LM1851 Features

* include circuitry that rapidly resets the timing capacitor in the event that noise pulses introduce unwanted charging currents and a memory circuit that allows firing of even a sluggish breaker on either half-cycle of the line voltage when external full-wave rectification is used Features Y Y Y Y Y
