RV4141A

Low-Power, Ground-Fault Interrupter

Features

Description

The RV4141A is

low-power controller for AC-

Powered from the AC Line

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.

Built-In Rectifier

Direct Interface to SCR

500μA 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

Compatible with 110V or 220V Systems

Available in an 8-Pin SOIC Package

Two sense transformers, SCR, solenoid, three resistors,

and four capacitors complete the design of the basic

circuit interrupter. The simple layout and minimum

component count ensure 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

independent 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.
