RV4145A  
Low Power Ground Fault Interrupter  
Features  
• No potentiomenter required  
• Direct interface to SCR  
• Supply voltage derived from AC line – 26V shunt  
• Adjustable sensitivity  
• Grounded neutral fault detection  
• Meets U.L. 943 standards  
• 450µA quiescent current  
• Ideal for 120V or 220V systems  
Description  
The RV4145A is a low power controller for AC outlet  
ground fault interrupters. These devices detect hazardous  
grounding conditions, such as equipment (connected to  
opposite phases of the AC line) in contact with a pool of  
water and open circuits the line before a harmful or lethal  
shock occurs.  
Contained internally are a 26V zener shunt regulator, an op  
amp, and an SCR driver. WIth the addition of two sense  
transformers, a bridge rectifier, an SCR, a relay, and a few  
additional components, the RV4145A will detect and protect  
against both hot wire to ground and neutral wire to ground  
faults. The simple layout and conventional design ensure  
ease of application and long-term reliability.
