RV4141AM-RV4141AMT
Low Power Ground Fault Interrupt Controller
Features Powered from the AC line Built-in rectifier Direct interface to SCR 500 µA quiescent current Precision sense amplifier Adjustable time delay Minimum external components Meets UL 943 requirements For use with 110V or 220V systems Available in 8 pin DIP or SOIC package
DescriptionThe 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.
Internally, the RV4141A contains a diode rectifier, shunt
regulator, precision sense amplifier, current reference, time
delay circuit, and SCR driver.
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.
