LM1851 Ground Fault Interrupter  
General Description  
Features

Internal power supply shunt regulator  
The LM1851 is designed to provide ground fault protection  
for AC power outlets in consumer and industrial environ-  
ments. 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 condi-  
tion. In addition to detection of conventional hot wire to  
ground faults, the neutral fault condition is also detected.  
Externally programmable fault current threshold  
Externally programmable fault current integration time  
Direct interface to SCR  
Operates under line reversal; both load vs line and hot  
vs neutral  
Y
Detects neutral line faults  
Full advantage of the U.S. UL943 timing specification is tak-  
en to insure maximum immunity to false triggering due to  
line noise. Special features include circuitry that rapidly re-  
sets the timing capacitor in the event that noise pulses intro-  
duce 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.
