3 1 Product Overview 1.1 Description The VG54123A is a semiconductor integrated circuit which is used as an earth leakage protection, which comprises voltage regulator, amplifier, comparator, controller and driver. 1.2 FEATURES When earth leakage is detected, pin outputs a high pulse at least 30ms Detector earth leakage include type AC Good input sensitivity for different type of earth leakage High noise protection against EMC Apply to 110V~220V(50Hz~60Hz) AC power supply 1.3 Pin Configuration (TOP VIEW) No. Pin Name Description 1 In1 Amplifier Input 1 2 In2 Amplifier Input NC No Connection 5 Amplifier Output 6 Dly Delay Output 7 Output drives SCR 8 VG54123A CM Leakage current protector chip 3

4 2 Function The VG54123A circuit for earth leakage protection device can be used to detect a difference current on line and neutral wires. Since the line and neutral wires pass through the center of the zero-current transformer(zct), only the differential primary current is transferred to the secondary, and the VG54123A s sense amplifier detects the secondary current. Earth leakage signal can be type AC. When leakage current which represented as RMS is above rated current (rms), Pin outputs a high pulse which lasts at least 20ms to drive SCR. 2.1 Schematic Diagram 2.2 ELECTRICAL CHARACTERISTICS test condition, -40 C ~85 C Parameter Symbol Test conditions Test circuit Min.
