UNISONIC TECHNOLOGIES CO., LTD GF4146 GROUND FAULT INTERRUPTER CMOS IC - DESCRIPTION The UTC GF4146 is a two-wire low-power controller for Residual Current Devices (RCD) and AC outlet Appliance Leakage Circuit Interrupters (ALCI) . The UTC GF4146 detects hazardous grounding conditions and open circuits the line before a harmful shock occurs. Internally, the UTC GF4146 contains a diode rectifier, 12V shunt regulator using a precision temperature-pensated bandgap reference, precision low VOS offset-sense amplifier, time delay noise filter, window-detection parators, and a SCR driver. With the addition of a minimum number of external ponents, the UTC GF4146 detects and protects...
