FAN4147 - Fairchild Semiconductor

FAN4147 Ground Fault Interrupter

The FAN4147 is a low-power Ground Fault Interrupter (GFI) controller for detecting hazardous current paths to ground and ground-to-neutral faults. The FAN4147 application circuit opens the load contacts before a harmful shock occurs. Internally, the FAN4147 contains a diode rectifier, precision bandgap 12V shunt regulator, precision lowVOS offset-sense ampli.
