| IL54123 GROUND FAULT INTERRUPTER EARTH LEAKAGE CURRENT DETECTOR Description The IL54123N/D is designed for use in earth leakage circuit interrupters for operation directly off the AC Line in breakers. It contains pre regulator, main regulator, after regulator, differential amplifier, level comparator, latch circuit. The input in the differential amp latch circuit. The input in the differential amplifier is connect to the secondary node of zero current transformer. The level comparator generates high level when earth leakage current is greater than some level. IL54123 Feature * Low Power Consumption (PD=5mW) 100V/200V * 100V/200V Common Built-in Voltage Regulator * High Gain Differential Amplifier * High Input Sensitivity (VT = 6.1mV Typ.) * Minimum External Parts * Large Surge Margin * Wide Operating Temperature Range (T= -40 to 85C) * High Noise Immunity * Meet U. L. 943 standards ORDERING INFORMATION IL54123N Plastic IL54123D SOIC IL54123S SIP-8 TA = -40 to 85 C for all packages.

Please decide constants R1, R2, C4, and C5 of a filter in order to keep at least 12V in Vs, when normal supply current flows. In this case, please connect C4 (more than 1 ) and C2 (less than 1 ). ZCT and load resistance RL of ZCT are connected between input pin and . In this case protective resistance (R3=100) must be insulted. Sensitivity current is regulated by RL, and output of amplifier shows in pin. External capacitor C1 between pin and GND is used for noise removal. When large current is grounded in the primary side (AC line) of ZCT, the wave form in the secondary side of ZCT is distorted and some signals doesn't appear in the output of amplifier. So please connect a varistor or a diode (2pcs.) to ZCT in parallel. Latch circuit is used to inspect the output level of amplifier and to supply gate current on the external SCR. When input pin becomes more than 1.1V (Typ.) latch circuit operates and supply gate current in the gate of SCR connected to the output pin. Pin can be used in the open state, but please connect capacitor (about 0.047 ) between pin and . Capacitor C6 between pin and GND is used to remove noise and is about 0.047 .
