To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Features

 No Potentiometer Required  Direct Interface to Silicon-Controlled Rectifier (SCR)  Supply Voltage Derived from AC Line – 26 V Shunt  Adjustable Sensitivity  Grounded Neutral Fault Detection  Meets U.L. 943 Standards  450 μA Quiescent Current  Ideal for 120 V or 220 V 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. A 26 V Zener shunt regulator, an operational amplifier , and an SCR driver are contained internally. With the addition of two sense transformers, a bridge rectifier, an SCR, a relay, and a few additional components; the RV4145A can 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. Figure 1. Block Diagram
