Common
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.
