FAN4146 Ground Fault Interrupter Description The FAN4146 is a low-power controller for AC outlet Appliance Leakage Circuit Interrupters (ALCI) and two-wire Residual Current Devices (RCD). The FAN4146 detects hazardous grounding conditions and open circuits the line before a harmful shock occurs. Internally, the FAN4146 contains a diode rectifier, precision bandgap 12 V shunt regulator, precision low VOS offset-sense amplifier, time delay noise filter, window-detection comparators, and a SCR driver. With the addition of a minimum number of external components, the FAN4146 detects and protects against a hot-wireto-ground fault. The minimum number of components and the small SUPERSOTt package allow for a small-form-factor, low-cost application solution.
