LM1851 Datasheet (UTC) - GROUND FAULT INTERRUPTER

LM1851, GROUND FAULT INTERRUPTER

The UTC LM1851 is designed to provide ground fault protection for AC power outlets in consumer and industrial environments.

Ground fault currents greater than a presentable threshold value will trigger an external SCR-driven circuit breaker to interrupt the AC line and remove the fault condition.

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. DIP-8 SOP-8 FEA
