LM1851 - Ground Fault Interrupter

This page provides the datasheet information for the LM1851, a member of the LM1 Ground Fault Interrupter family.

Datasheet Summary

Description

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

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 Y Internal power supply shunt regulator Externally programmable fault current threshold Externally programmable fault current integration time Direct interface to SCR Operates under line reversal b.
