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.
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 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.
