RV4141A  
Low Power Ground Fault Interrupter  
Description  
Features  
The RV4141A is a low power controller for AC receptacle  
ground fault circuit interrupters. These devices detect  
hazardous current paths to ground and ground to neutral  
faults. The circuit interrupter then disconnects the load from  
the line before a harmful or lethal shock occurs.  
• Powered from the AC line  
• Built-in rectifier  
• Direct interface to SCR  
• 500 µA quiescent current  
• Precision sense amplifier  
• Adjustable time delay  
Internally, the RV4141A contains a diode rectifier, shunt  
regulator, precision sense amplifier, current reference, time  
delay circuit, and SCR driver.  
• Minimum external components  
• Meets UL 943 requirements  
• For use with 110V or 220V systems  
• Available in 8 pin DIP or SOIC package  
Two sense transformers, SCR, solenoid, three resistors and  
four capacitors complete the design of the basic circuit inter-  
rupter. The simple layout and minimum component count  
insure ease of application and long term reliability.  
Features not found in other GFCI controllers include a low  
offset voltage sense amplifier eliminating the need for a  
coupling capacitor between the sense transformer and sense  
amplifier, and an internal rectifier to eliminate high voltage  
rectifying diodes.  
The RV4141A is powered only during the positive half  
period of the line voltage, but can sense current faults inde-  
pendent of its phase relative to the line voltage. The gate of  
the SCR is driven only during the positive half cycle of the  
line voltage.
