www.fairchildsemi.com
Features
• Powered from the AC line
• Built-in bridge rectifier
• Direct interface to SCR
• 350 mA quiescent current
• Adjustable trip current
• Adjustable time delay
• Minimum external components
• Meets UL 943 requirements
• Specifically for two-wire systems
• For use with 110V or 220V systems
Description
The RV4140A is a low power controller for AC outlet
appliance leakage circuit interrupters. These devices detect
hazardous current paths to ground such as an appliance
falling into water. The interrupter then open circuits the line
before a harmful or lethal shock occurs.
Internally, the RV4140A has a diode bridge rectifier, zener
shunt regulator, op amp, current reference, time delay circuit,
latch and SCR driver.
An external sense transformer, SCR, relay, two resistors
and three capacitors complete the design of the circuit
interrupter. The simple layout and minimum component
count ensure ease of application and long term reliability.
