1 / 4 page - + - + VFB Signal Common Filter 20k W 10k W Bias Gnd Detect 4.7k W 50k W AmpOUT +VS SCR Trigger - + The CS294 is an AC outlet ground fault interrupter controller IC. The IC detects the presence of haz- ardous grounding conditions and open circuits the AC line before a dangerous shock can occur. The CS294 contains an operational amplifier, an SCR driver and a 24V zener shunt regulator. Two sense coils, a bridge rectifier, a relay and an SCR are required as external components. The completed inter- rupter circuit can detect and protect against both hot wire to ground faults and neutral wire to ground faults. The CS294 is built on a 30V bipolar process and is available in 8 lead DIP packages.
