CS294 - Ground Fault Interrupter

Datasheet Summary

Description

The CS294 is an AC outlet ground fault interrupter controller IC.

The IC detects the presence of hazardous 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.

CS294 CS294 Ground Fault Interrupter Description The CS294 is an AC outlet ground fault interrupter controller IC. The IC detects the presence of hazardous 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 interrupter 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.
