Preliminary

LINEAR INTEGRATED CIRCUIT

GROUND FAULT

INTERRUPTER



DESCRIPTION

The UTC GF4147 is a low-power Ground Fault Interrupter

controller for detecting hazardous current paths to ground and

ground-to-neutral faults. The UTC GF4147 application circuit

opens the load contacts before a harmful shock occurs.

The UTC GF4147 circuitry has a built-in rectifier and shunt

regulator that operates with a low quiescent current. The low-V_OS

offset-sense amplifier allows direct coupling of the sense coil to

the amplifier’s feedback signal. This eliminates the large 50/60Hz

AC-coupling capacitor.


